Project Topic: A THz pulse-radiating array for long-range high-speed wireless communication and hyper-spectral imaging.
A novel THz pulse generation technique, Direct Digital-to-Impulse (D2I), capable of radiating high-power picosecond pulses, is introduced in this project. Based on this architecture, a digitally programmable THz pulse-radiating array in silicon is proposed, which can radiate 1.9ps pulses with 10kW peak pulse EIRP, 100GHz repetition rate, and 3-bit amplitude modulation capability. The array will form narrow beams of broadband THz pulse radiation, which can be used in a high-resolution, long-range active spectral imaging system. In addition, this array will enable a 300Gbps wireless link over a 300m distance. This will be the first broadband, high-power, and highly directive beam-steerable THz source with a repetition rate of 100GHz and integrated digital programmability.
Project Topic: Innovative solutions for adaptive transceiver front ends/mobile commutations for internet of things.
By 2020, the Internet of Things (IoT) will consist of 50 billion resource-constrained “Smart Things” that will provide critical every-day services in applications as diverse as Smart Cities, Smart Production, or Connected Cars. These applications require a dependable IoT despite hostile environments and deliberate attacks both on software and hardware level (tunable front ends – filters and antennas), where dependability summarizes aspects such as reliability, safety and security that enable users to put trust into the IoT. Today’s approaches to construct an IoT do not guarantee dependability, that is why the envisaged research activity on advanced front ends founds a perfect match with the current challenges of IoT. During the three-four years the doctoral program, current limitation of filters and antennas will be analyzed to propose innovative design solutions in the field of “Internet of Things and mobile communication” in order to improve the state of the art, propose new tuning methods and miniaturization techniques.
Project Topic: Integrated solar and radio-frequency energy harvesting for the internet of everything.
To reach the level of ubiquitous deployment expected for the Internet of Everything (IoE), energy harvesting is a promising and necessary functionality for providing power to a high volume of wireless devices, and will require harvesting from multiple sources to increase the lifetime and reliability of IoE devices. The research objective of this project is to develop a compact module to harvest both solar energy as well as radio-frequency (RF) energy with a single physical aperture, enabling dedicated RF and ambient solar energy harvesting within a compact form factor. This will be accomplished with a 3D antenna design that enables high optical transmission without compromising the radiation efficiency of the RF antenna, such that it may be mounted above a solar panel and provide stable power delivery for IoE functionality.

Project Topic: Generalized reconfigurable mm-Wave Tx architecture and antenna interface with active impedance synthesis.
Classical methods of fixed-frequency narrowband transceivers need to be fundamentally rethought, as the next generation communication paradigm seems to be more heterogeneous not only in terms of frequencies, but also the devices they connect and serve. In such a connected paradigm, where techniques such as massive MIMO is expected to play a role, current architectures are not scalable. My research focuses on new methods to enable programmable, frequency-agile, waveform-agile transmitters without sacrificing efficiency. Tied to this, we also want to address the fundamental trade-offs between energy efficiency and spectral efficiency through new methods of network synthesis that can be mapped into transmitter architectures. The vision is to enable such approaches in reaching towards field programmable / universal transmitter architectures.
Project Topic: Novel ultra-high speed terahertz communication system on silicon.
The demand of wireless links throughput is expanding drastically nowadays. However, the spectrum resources we can utilize is becoming more and more limited in conventional radio frequency bands. On the other hand, vast unallocated spectrum exists in terahertz range, which can easily provide an ultra-wide bandwidth for very fast wireless communication. The line-of-sight nature of terahertz communication also makes it more secure compared to low frequency broadcasting. My project is majorly about exploring and developing novel modulation schemes, high efficiency transmitter and high sensitivity receiver architectures as well as high performance terahertz circuit blocks (oscillators, switches, mixers, etc.) that are suitable for integration on silicon to implement high performance terahertz wireless communication systems for future applications.
Project Topic: High power submillimeter-wave varactor frequency multipliers based on quasi-vertical Schottky diodes.
Submillimeter-wave technology has received substantial attention in the past decades, for its use in a variety of important applications, including radio astronomy, spectroscopy, plasma diagnostics, radar, imaging, and potentially communications. One of the factors that limit the widespread of this technology is the lack of high power solid state sources, often coined the “terahertz gap”. Frequency multipliers are the best candidates to provide a source of stable, reliable, and compact power at terahertz. However, their efficiencies significantly degrade after each multiplication stage, leading to very low powers at 1 THz. One way of addressing this issue is to increase the input power to the first multiplication stage. Thus, power handling has become a major concern. This project proposes a transformative approach to improve the thermal management and output power of frequency multipliers, by investigating new device geometries, fabrication processes, design innovations, and electrical and thermal characterization techniques. The end goal is to prototype and characterize a 520 GHz multiplier chain, with 10 mW of output power.
Project Topic: Novel compact zero-power wireless sensors based on the harmonic radar principle, featuring low environmental impact and high integrability, for the next generation IoT applications.
New emerging trends in RF design, such as Internet of Things (IoT), ubiquitous intelligence and wearables electronics, call on next generation sensors to be wireless, energetically autonomous, able to operate in variable environments without needing periodical maintenance and be conformal to the hosting object.
This research is dedicated to the development of a particular class of zero-power wireless sensors, which relies on the harmonic radar principle. The potential of the proposed approach is explored by means of a theoretical analysis and optimization of the single building blocks of the tag, i.e., the harmonic generation, the antenna system and the highly innovative sensors. Thanks to the adoption of highly-scalable, simple and robust architectures, the solutions explored in the project are intended to be suitable for a large-scale mass production. The developed wireless sensors, being able to test different properties, both mechanical and chemical, can be of interest for various scenarios and industrial applications. All the proposed sensor tags are designed to be fabricated on unconventional flexible materials by using innovative technologies, in order to reduce their environmental impact and ease their integration with common objects.

Project Topic: Near-field microwave sensor for contact-less ultra-wide-band (UWB) dielectric spectroscopy.
Self-sustained microwave dielectric spectroscopy (MDS) of liquids with μ-level sample volumes has attracted special attention over the past decade because of the vast area of applications, from oil exploration and processing, to food/drug safety, and chemical or biological sensing. In such systems, the fluidic carrying the chemical under test is in direct contact with the sensing element, which makes the sensor hardly re-usable. Moreover, MDS operating in the frequency domain is usually time-consuming. However, time-domain spectroscopy can reduces the time of the measurement procedure considerably, since a broad range of frequencies can be covered in a single measurement trial. The proposed research plan addresses the need for compact contact-less MDS sensor performing in time domain.
Project Topic: Enabling fully-integrated magnetic-free non-reciprocal antenna interfaces by breaking lorentz reciprocity.
The next generation of wireless communication networks is targeting orders of magnitude higher data rate than today’s systems. Various new emergent technologies are under investigation to enable the 5G revolution, such as full-duplex wireless. Enabling these technologies require a re-evaluation and redesign of various layers of the communication system, from the physical (PHY) layer all the way up to the application layer. Specifically within the PHY layer, the conventional reciprocal antenna interfaces of current wireless systems impose fundamental limitations on the radio front-end design and their applicability to these emergent technologies. The aim of this research project is to investigate, develop and demonstrate new fully-integrated magnetic-free non-reciprocal antenna interfaces as well as novel receiver front-end design techniques which benefit from the nonreciprocal behavior of these antenna interfaces.

Project Topic: Active and passive device characterizations on CMOS for ultra-high data-rate millimeter-wave and sub-terahertz wireless transceivers.
There is an urgent requirement for ultra-high data-rate wireless systems in today’s world for several different applications; such as backhaul networks. Eventually 100Gb/s or more wireless data-rates are needed to be achieved. Wideband (mm-wave and sub-terahertz) and higher modulation complexity transceivers can achieve the aim, such as our work achieving 56Gb/s at W-band. For these kinds of systems, the requirements are very challenging, and accuracy of the devices greatly affects the end product. For this reason, accurate active and passive device designs, characterizations and modeling of these devices are required. This research focuses mainly on, single-ended and differential de-embedding, transistor layout considerations and modeling, two- and more than two-port passive device characterization methods from DC up to more than 300GHz frequency region.
Project Topic: Flexible implant antenna for thermotherapeutic cancer treatment
Radiation therapy and hyperthermia are two common procedures along with chemotherapy in current clinical practices to treat different type of cancers. Chemotherapy causes harmful and painful effects to patients and is usually considered for the last resort. Use of radiation therapy can lead to serious long-term side effects. On the contrary, hyperthermia treatment does not involve harmful radioactive radiation, and can be applied by several methods. One of the most common method is microwave tumor ablation, where a tumor is identified with imaging guidance and exposed to microwave energy by a thin microwave antenna placed into the tumor through surgical operation. The electromagnetic energy radiated by microwave source agitates the polar water molecules trapped in the tissues, which produces heat due to friction between the molecules. The major shortcoming of this approach is patient needs to undergo multiple surgeries to insert the microwave antenna probe into the tumor for every treatment. The proposed research will develop a new method for hyperthermia treatment using minimally invasive surgery. The aim of the research focuses on a study and development of biodegradable miniature flexible implant design to receive microwave energy for hyperthermia.
Project Topic: Metamaterial-inspired radiofrequency system design for human head imaging at ultra-high field strength MRI

The proposed research will focus on the development of new strategies to overcome the limitations of the commonly used RF systems. It will help enable the potential benefits of the UHF MRI such as increased special and/or temporal resolution. The researcher aims to use her research work to facilitate neurological studies and reveal mesmerizing mysteries of the human brain.

Project Topic: A CMOS multi-functional cellular thermal actuation/sensing array for reconfigurable localized cell heating and manipulation
Applying thermal stress on cells or tissues has a wide variety of biomedical applications. For example, hyperthermia induced by microwave ablation is proven to be an effective method for cancer treatment. Heat shock can effectively reduce the amplitudes and durations of the action potentials in neuron axon hillocks to block the neural signal transmission in a neural network. However, existing thermal applicator devices are typically designed and operated for macroscopic scale clinical applications. We propose a CMOS cellular thermal actuation/sensing array chip for microscopic cellular analysis and characterizations. The cellular thermal actuator array can realize, for the first time, localized heat transfer to the individual cells or cell clusters for cell-/tissue-level studies. In parallel, on-chip temperature sensors are implemented in each thermal actuator pixel to accurately monitor the local temperature distribution. Our platform also supports dielectrophoresis (DEP) operation for cell sorting and manipulation. The proposed CMOS cellular thermal actuation/sensing array platform will serve as a novel low-cost cellular analysis platform, directly applicable for a plethora of high-impact biomedical applications, such as cancer studies, cell-based assays, drug screenings, and neural network characterizations.
Project Topic: Development of Frequency Reconfigurable Wireless Power Scavenging System for the Telemetry of Self-sustainable Implantable Sensors
The research objective of this project is to develop a novel and simple approach of designing both high-efficiency and miniaturized Wireless Power Scavenging (WPS) system for the telemetry of implantable sensor network using patterned permalloy (Py) thin film embedded in engineered substrate. Incorporating a frequency reconfigurable transmitting antenna into the WPS system, the frequency of the transmitted RF power can thus be tuned to adapt to the frequency shift of the rectenna in sensor network to ensure the maximum power harvesting efficiency. Using patterned Py thin film embedded in engineered substrate, both the frequency reconfiguration and the miniaturization of the devices can be achieved simultaneously. The development of this kind of special substrate has been proved to be an efficient and cost-effective approach to design both tunable and miniaturized devices without deteriorating the performance too much. The research plan of the proposed system has two major goals: (i) Design and implementation of a miniaturized self-sustainable power scavenging system including: the development of miniaturized implantable antenna; development of highly-efficient rectenna; (ii) Design of frequency reconfigurable transmitting circuits for adaptive power harvesting.

Project Topic: Continuous-Wave Radar Sensor for Accurate Respiration Measurement in Motion-Adaptive Cancer Radiotherapy
Project Description: Continuous-wave (CW) radar sensor has been proposed for accurate respiration measurement in motion-adaptive cancer radiotherapy. It provides a non-contact and non-invasive approach for respiration measurement. Instead of measuring the marker, it directly measures the periodic motion of the body, which has better correlation with the lung tumor motion. Moreover, the radar system is insensitive to clothing and chest hair, due to microwave penetration, making it better than the existing contact devices that are sensitive to the surrounding environment. The signal distortion problem in respiration measurement has been thoroughly analyzed. A DC-coupled radar sensor with adaptive coarse-tuning and fine-tuning architectures is proposed for complete respiration pattern measurement without any distortion. The DC-coupled radar will use a two-stage variable gain amplifier (VGA) with software-configured DC tuning architecture integrated in AMI 0.5-μm CMOS process. The radar sensor system will be clinically evaluated in the Southwest Cancer Treatment & Research Center, Lubbock, TX.
Project Topic: A Wearable Health-Monitoring System for Medical Emergency Alerts Based on Textile Radiators and Indoor Radar supporting Fall-Detection, Localization and Telemetry
Project Description: Falls are the leading cause of accidental deaths for home-bound and semi-mobile seniors over 65 years. Thus, it is imperative that a cost-effective continuous health monitoring system is developed for such group to enable prompt and automatic alerts to emergency response teams. This work intends to design and develop such system applicable for indoors and outdoors, consisting of two sub-systems; first an indoor fall-detection radar system; and secondly, a cost- effective wearable system. This combined system is expected to provide fall detection capability, target localization and wireless telemetry alerts back to a base station. Moreover, the wearable system is intended to be developed fully using textiles, which will guarantee users' comfort, besides being immune against on-body absorption. A novel method of mutual-coupling reduction and back-radiation suppression using bandgap structures is proposed to be investigated.
Project Topic: Wearable Front-end design of in vivo L-Glutamate Neurotransmitter Monitoring Systems
Project Description: The research project focuses on developing a wireless system for in vivo monitoring L-Glutamate, a predominant excitatory neurotransmitter in mammalian central neuronal system. A miniature and implantable needle-like probe with multiple sensing electrodes will be fabricated using MEMS (micro-electro mechanics system) technology to sense the L-Glutamate signals at different brain sites. Sensors with electrodes modified with iridium oxide nanostructure are expected to have significant improvement in sensitivities. The signals will be recorded, conditioned and amplified using an on-site bipotentiostats, which will be designed and optimized for small current measurement. An RF wireless transceiver will be implemented to transmit signals from the wearable bipotentiostat to the recording base station. The use of RF wireless communication for signal transmitting reduces noises, body motion artifacts and inconvenience for animals and patients in long term experiments. The ability to observe and quantify L-Glutamate signals instantaneously and wirelessly helps us to study the correlation between L-Glutamate and many neuronal diseases such as Parkinson’s disease, Alzheimer’s disease, neurodegeneration, and depression.
