Progresses towards the application of terahertz technologies

Abstract

Science and technologies based on terahertz radiation have developed rapidly over the recent decades, which inspires the application attempts and research of terahertz technologies in several fields. Compared with the microwave or infrared waves, terahertz waves are of higher frequencies and lower photon energy. A variety of dielectrics are transparent with the terahertz radiation. Status and progresses in the field of terahertz communication, biological and medical application, non-destructive testing, and defense and security imaging are discussed in this work, as well as the challenges for real-life applications.
