Implantable Wireless Medical Devices and Systems
Radio frequency identification (RFID) has been utilized to increase efficiency and care quality in hospitals for patient information management, drug and equipment inventory, scheduling and staffing. To further improve healthcare, enable new diagnosis and treatment while aiming to reduce costs, major technical challenges still exist. Limited sampling and acquisition of physiological parameters during the interaction period for caregivers and patients provide incomplete information about the patients. Better care with higher diagnosis accuracy can be provided if more and time-lapsed data can be obtained without causing patients discomfort or limiting their mobility. Meanwhile, patient data documentation has become too cumbersome. The lack of portability and timely accessibility of the physiological information prevent real-time management by caregivers and/or patients themselves.
Wireless technologies bring promising solutions to the aforementioned issues. Low-cost portable wireless electronics have made significant impacts to our societies. Furthermore, recent advances in micro- and nano-technologies provide unique interfacing functionalities to human tissues, and advantages such as miniaturization and low power consumption enabling novel applications in medicine and biological studies. Interfaces between biological objects and electronics allow quantitative measurement and documentation of physiological and biochemical parameters, and even behaviors. The interfaces also provide direct control or modification of cells, tissues, or organs by the electrical circuits making it possible to manage chronic diseases with a closed loop between biological objects and computers. With wireless communication, implantable devices and systems make the interfacing possible for freely behaving animals or patients without constrains, discomfort or limits in mobility. This increases the study or diagnosis accuracy in realistic environments as well as permits remote synthesis of physiological functions and delivery of therapeutic treatment. Furthermore, wireless communication enables networks for ubiquitous access to physiological information at various system levels either within one’s body or within a group of patients for better deterministic and statistical understanding of issues in complex systems.
The lecture focuses on the development of wireless micro devices and systems for clinical and biological applications. The systems are based on technology platforms such as wireless energy transfer for batteryless implants, miniature electrochemical sensors, nanoparticle modified surfaces, microelectromechanical system devices and microwave communication. In this talk, several implantable wireless diagnosis and therapeutic treatment systems will be discussed. An integrated wireless body network for chronic pain management has been demonstrated with wireless closed-loop integration of neurorecorders to recognize pain signals and neurostimulators to inhibit pain. Batteryless endoluminal sensing telemeter architecture has been demonstrated for an esophagus implant for remote diagnosis of gastroesophageal reflux disease (GERD), an endoscopically-implantable wireless gastro-stimulator for gastroparesis management, and a wireless bladder volume monitoring implant for urinary incontinence management. These applications enable new medicines to improve human welfare and assist better living.

Circuit to System Level Practical Microwave Education
Recent years have seen rapid changes in RF techniques as well as technology. This trend is continuing enabling the use of increasingly higher RF frequencies with their inherent advantages of smaller size components and larger bandwidth. In particular, the use of planar circuit architecture and integration using micro-machining technology has opened up new opportunities in terms of reduction in cost, weight, volume, power consumption as well as extension of operating frequencies. In keeping with the advances in technology, the design approach is also undergoing a rapid change through improved digital signal processing (DSP) techniques and CAD tools. Thus the scope of RF Design Techniques and Technology, that was confined to lower microwave frequency bands (~10 GHz), has expanded to encompass the millimeter wave frequency band (30-300 GHz). This paradigm places new demands on Microwave Education. The responsibility of microwave educators today is to drive students beyond the basic concepts to circuit and system level practical hands-on-education in order to produce highly skilled and motivated wireless engineers who are directly usable to the industry.
The present talk is focussed to motivate students to opt for career in RF and Microwave Engineering. Starting with the behavior of conventional circuit elements at RF and Microwave frequencies and describing equivalent lumped circuit models of distributed transmission line elements, different technologies available to a designer to built Microwave and Millimeter Wave Integrated Circuits and subsystem will be presented. Starting from conventional microstrip technology, other key technologies including suspended stripline, dielectric integrated guides, fin line, MMIC, RF CMOS and LTCC will be briefly described. Design methodology including use of existing CAD tools leading to development of several high performance components/ subsystems at lower microwave frequencies as well as millimeter wave frequencies centered around 35 GHz, 60 GHz and 140 GHz will be presented. Micromachining has recently been applied to millimeter wave field to create low loss and high performance components and antennas. Methodology for the design, development and fabrication of passive components, antennas and switches at millimeter wave frequencies will be described next. Concept of developing reconfigurable RF circuits using either variable capacitors or switches will then be briefly presented. Future research activities in our group in the area of RF Nanotechnology will also be discussed. In the end, practical demonstration of several pre-fabricated passive and active components at Microwave frequencies will be given using a handheld network analyzer and special custom made test jigs.

Radio-Frequency Nanoelectronics – Bridging the Gap between Nanotechnology and R.F. Engineering Applications
Abstract
In view to the new epochal scenarios that nanotechnologics disclose, nanoelectronics has the potential to introduce a paradigm shift in electronic systems design similar to that of the transition from vacuum tubes to semiconductor devices. Since many nano-scale devices and materials exhibit their most interesting properties at radio-frequencies (RF), nanoelectronics provides an enormous and yet widely undiscovered opportunity for the microwave engineering community.
The lectures presents a technical overview of some of the main research fields of nanoelectronics for RF applications, i) showing the potentialities offered by emerging nano-scale materials (e.g. carbon nanotubes, graphene), ii) highlighting unprecedented microwave, millimeter-wave and THz devices and systems, iii) focusing on critical technologic aspects.
While the advancement of research in this area heavily depends on the progress of manufacturing technology, still, the global modeling of multi-physics phenomena at the nanoscale is crucial to its development. Modeling, in turn, provides the appropriate basis for design.
The aim of this effort is to close the gap between the nanosciences and a new generation of highly integrated and multifunctional devices, circuits, and systems, for a broad range of applications and operating frequencies, up to the optical region. This aim can be achieved by using the panoplia of microwave engineering at our disposal.

Towards Greener Smartphones with Microwave Measurements
Abstract
Today's smartphone handsets offer a wide range of functions (phone, GPS, Bluetooth, WiFi, .) to customers, although are still perceived as expensive and energy consuming (requiring a daily recharge). The aim of this talk is to show how microwave measurements impact smartphone design. By optimally engineering the type of measurements made before and after design (linear, nonlinear, loadpull, modulation, .), the efficiency of the design process not only increases, but tougher specifications such as smaller form factor and lower energy consumption can be met more easily. This observation is especially valid in the design of green multi-mode wireless radios, due to the delicate balance between energy efficiency and linearity (that is, cross talk between channels).
The didactic level of this talk will be adapted to the background of the audience.

Behavioural Modeling & Linearization of RF Power Amplifiers
Abstract
In cellular wireless communications systems, the RF power amplifier (PA) in the transmitter must be as efficient as possible, to minimize energy costs, to prolong battery life, and for ‘green’ considerations. Modern spectrally-efficient, digitally-modulated signals such as LTE and UMTS present a challenge for efficient RF PA design, and the power amplifier architectures that are adopted to achieve this goal are generally very nonlinear, and so some form of linearization technique is necessary.
The increasing use of linearization techniques, and especially the emergence of high speed digital processing as an enabling technology to implement digital pre-distortion (DPD) of the PA input signal, represent an important paradigm shift in PA design. The PA component can now be designed with more emphasis on power and efficiency, without the traditional constraints of meeting stringent linearity specs simultaneously. Understanding the utility of a linearizer to obtain optimum efficiency has thus become a new subject area in modern RF PA design.
The system-level design of linearized PA transmitters requires accurate models to achieve the optimal performance. Behavioural modeling is used to describe the PA and linearizer at this level of the design. In this lecture, we shall present some approaches to the behavioral modeling of nonlinear dynamical systems that can be used to model RF PAs; particular emphasis will be given to the treatment of memory effects. Some common mathematical and systematic approaches to model generation will be presented, to obtain accurate but compact nonlinear dynamical models. A brief description of some characterization techniques will be included. These same nonlinear modeling techniques can be applied to the design of successful pre-distortion algorithms. We shall illustrate the overall structure of a linearized transmitter using several DPD architectures, and we shall present various approaches to adaptive pre-distortion, considering such features as convergence, signal bandwidth, accuracy, and cost.

Microwave Near-field Imaging of Human Tissue: Hopes, Challenges, Outlook
More than 40 years ago, Larsen and Jacobi experimented with microwaves in the imaging of canine kidney. Their pioneering work triggered high hopes for a new diagnostic modality in medicine but also identified serious challenges. Research effort in this area continues unabated, focused especially on early-stage breast-cancer detection. The need for alternative cancer diagnostic tools is urgent and perceived worldwide as a high priority for research and development. Yet the very few clinical trials of experimental microwave imaging systems have not satisfied the requirements of today’s medical diagnostics. This talk briefly reviews past and recent developments in near-field microwave methods for tissue imaging. In the context of these developments, the major challenges are discussed – challenges which have so far prevented microwave imaging from becoming a clinically viable modality. Promising new directions of research are described that have the potential to bring about a breakthrough. These include advances in hardware design and characterization (sensor arrays, custom and laboratory measurement instrumentation), methodologies for tissue-parameter characterization, and the development of data-processing and reconstruction algorithms. Many of these new developments draw upon recent successes of microwave and millimeter-wave imaging systems used for concealed-weapon detection, through-the-wall imaging and underground surveillance. Thus it is shown how the ever expanding field of microwave imaging is converging to address some of society’s most urgent needs.

Graphene-based Electronics for RF Communications and Sensing
Electrical engineering is at a crossroads. For the last fifty years, semiconductors have been driving the development of information technology, which has completely transformed our society. Conventional electronics, however, is reaching scaling and performance limits which jeopardizes future developments. New materials with unique properties are necessary and graphene, a one atom thick layer of sp2 bonded carbon, is at the top of potential candidates.
Graphene not only has outstanding transport properties, but it also shows many unique properties not found in any other high performance electronic material. It is flexible, transparent, ultimately scalable, easily transferable to any surface, and its ambipolar conduction offers new possibilities for advanced electronics. In this talk, we describe how the use of these properties allows the development of new devices, which can overcome some of the main limitations of traditional electronics in terms of sensitivity, maximum frequency, and linearity. Several novel devices will be discussed for RF communications and remote sensing, including graphene frequency multipliers, graphene RF mixers and graphene chemical sensors.

Commercial Applications for RF MEMS
Radio frequency micro-electro-mechanical systems (RF MEMS) have been heralded as a technology fit for the 21st century, offering unsurpassed RF performance over more conventional solid-state electronic devices. In recent years, this technology has seen a rapid rate of expansion because of its potential for advancing new products within a broad range of applications; from ubiquitous smart sensor networks to mobile handsets. Indeed, within the US, Asia and Europe, R&D is almost at fever pitch. The high levels of investment come second only to the expectations for commercial exploitation. The first RF MEMS device was reported 30 years ago by IBM. After experiencing the peak of inflated expectation in 2003 and subsequenttrough of disillusionment in 2005, RF MEMS switches have emerged into the slope of enlightenment. They are now commercially available on the open market, offering new solutions for realizing high performance reconfigurable microwave circuits and systems. A major new book, entitled Advanced RF MEMS (edited by the speaker), is scheduled for publication at the beginning of 2010. This lecture will explain the many facets of this technology and demonstrate how RF MEMS can move itself out of the laboratory and into real commercial applications.
Stepan Lucyszyn PhD, DSc, FIEE, FInstP, FEMA, is currently a Reader (Associate Professor) in Millimetre-wave Electronics at Imperial College London.

Liquid Crystal Polymer for Microwave and Millimeter-Wave Multi-layer Packages and Modules
Hermetic packages are used to protect microwave and millimeter-wave monolithic integrated circuits against harsh environmental conditions, including changes in atmospheric pressure, humidity, moisture, and other natural hazards that would otherwise disrupt electrical connections or damage delicate electronics. Microelectromechanical systems (MEMS) require hermetic packaging to prevent against contaminating particles and moisture. Hermetic packages have a fine helium leak rate of ~1x10-11 atm-cc/sec and are known to provide the reliability in harsh environments. Current hermetic packages are based on metal and ceramic materials. Ceramic and metal packages are heavier, bulkier, and more expensive than organic counterparts. At the wafer-level packaging, high temperature wafer bonding is used to form hermetic cavities that result in tall structures. While organic packaging technology cannot provide true hermeticity, can it have a low enough leak rate to achieve competitive reliability? This is referred as reliability without hermeticity or near hermetic packaging.
In this lecture, we will review the concept of hermeticity and near-hermeticity in electronic packages. Liquid Crystal Polymer (LCP), which has permeation close to glass, will be introduced as the next generation organic material for near-hermetic packaging. We will discuss results of LCP material characterization. We will then present the development of sealing techniques of LCP onto LCP and LCP onto semiconductor materials to form near hermetic cavities for housing MEMS and MMICs. Using the newly developed sealing techniques, we will demonstrate LCP wafer-level packages, surface mount packages and multi-chip modules to 40 GHz. Examples of wafer-level packages include the lamination of LCP onto Si to cap or package RF MEMS switches and a phase shifter with LCP-packaged MEMS. We will also present the development of low-loss surface mount LCP packages to 40 GHz. These surface mount packages are designed with novel feedthroughs that achieve a measured insertion loss of ~0.2 dB to 0.4dB up to 40 GHz and provide embedded filters. We will discuss bond wire compensation schemes, package to printed circuit board transition design techniques, electrical repeatability, and thermal performance of millimeter-wave surface mount packages. Reliability evaluation will be presented to demonstrate the robustness and reliability of LCP packages. Examples of the environmental tests include 1000 hours of 85oC and 85% humidity, temperature cycles, thermal shock, etc. Finally, we demonstrate the development of compact wide bandwidth passive components, multi-chip modules, and phased array antennas in multi-layer LCP boards at Ka-band.

Inkjet-Printed Paper/Polymer-Based "Green" RFID and Wireless Sensor Nodes: The Final Step to Bridge Cognitive Intelligence, Nanotechnology and RF?
In this talk, inkjet-printed flexible antennas, RF electronics and sensors fabricated on paper and other polymer (e.g.LCP)substrates are introduced as a system-level solution for ultra-low-cost mass production of UHF Radio Frequency Identification (RFID) Tags and Wireless Sensor Nodes (WSN) in an approach that could be easily extended to other microwave and wireless applications. The talk will cover examples from UHF up to the millimeter-wave frequency ranges.
A compact inkjet-printed UHF "passive-RFID" antenna using the classic T-match approach and designed to match IC's complex impedance, is presented as a the first demonstrating prototype for this technology. Then, Prof. Tentzeris will briefly touch up the state-of-the-art area of fully-integrated wireless sensor modules on paper or flexible LCP and show the first ever 2D sensor integration with an RFID tag module on paper, as well as numerous 3D multilayer paper-based and LCP-based RF/microwave structures, that could potentially set the foundation for the truly convergent wireless sensor ad-hoc networks of the future with enhanced cognitive intelligence and "rugged" packaging.
Prof. Tentzeris will discuss issues concerning the power sources of "near-perpetual" RF modules, including flexible minaturized batteries as well as power-scavenging approaches involving thermal, EM, vibration and solar energy forms.
The final step of the presentation will involve examples from wearable (e.g. biomonitoring) antennas and RF modules, as well as the first examples of the integration of inkjet-printed nanotechnology-based (e.g.CNT) sensors on paper and organic substrates. It has to be noted that the talk will review and present challenges for inkjet-printed organic active and nonlinear devices as well as future directions in the area of environmentally-friendly ("green") RF electronics and "smart-skin' conformal sensors.
Professor Manos M. Tentzeris received the Diploma Degree in Electrical and Computer Engineering from the National Technical University of Athens ("Magna Cum Laude") in Greece and the M.S. and Ph.D. degrees in Electrical Engineering and Computer Science from the University of Michigan, Ann Arbor, MI and he is currently a Professor with School of ECE, Georgia Tech, Atlanta, GA. He has published more than 420 papers in refereed Journals and Conference Proceedings, 5 books and 19 book chapters.
Dr. Tentzeris has helped develop academic programs in Highly Integrated/Multilayer Packaging for RF and Wireless Applications using ceramic and organic flexible materials, paper-based RFID's and sensors, biosensors, wearable electronics, inkjet-printed electronics, "Green" electronics and power scavenging, nanotechnology applications in RF, Microwave MEM's, SOP-integrated (UWB, multiband, mmW, conformal) antennas and Adaptive Numerical Electromagnetics (FDTD, MultiResolution Algorithms) and heads the ATHENA research group (20 researchers).

Power Handling and Temperature Compensation Design for Passive Microwave Devices
Modern communication and radar transmitter systems require high performance RF/Microwave devices and components, to improve communication and detection range. The increase in range is accomplished by increased transmitted power and higher receiver sensitivity. The increased transmitted power requires the engineer to estimate the transmitter's power handling capability as part of the design process. In addition, the engineer has to meet several competing requirements at a specified pressure level, such as containment of transmitted bandwidth (wide or narrow, i.e., reduce adjacent channel spill over), minimize group delay variations, and reduce performance drifts with environmental condition changes (e.g., temperature, pressure, and humidity). When designing devices for these high-power operations, one often has to take into account the following effects: multipactor and ionization breakdown, passive intermodulation interferences and thermal-related issues such as temperature compensation. This talk will elaborate the physics background, technical challenges and design methodologies. It will also cover the clever use of both circuit and electromagnetic modeling techniques. Numerous examples will be presented from those widely used in the industry. The method presented is general and is applicable to all device types.
The following topics are also offered by the author: "Overview of High Performance Microwave Filter Technologies", "Miniaturization of Microwave Filters using Predistortion and Dissipative techniques" and "Electromagnetic Simulator for the Design of Large Microwave Circuits ."
