The IEEE Transactions on Terahertz Science and Technology is the preeminent publication concerning terahertz science and technology, with an acceptance rate of 35% and published bimonthly. The Transactions is a hybrid journal and offers open access publishing options. The Transactions accepts both long, fully developed regular papers, in addition to shorter, more timely manuscripts; these papers will appear in our "THz Letters" section. Tutorial and review papers are also published, as well as occasional special issues, which present collections of papers that examine particular areas with a wider scope and more in-depth. Please, note that the IEEE Transactions on Terahertz Science and Technology does not accept incremental submissions and theory, measurements, and simulations should be supported by careful comparisons.
