The study of THz wave propagation feature in atmosphere

Haixia Cui, Jianquan Yao, Chunming Wan

Abstract

Terahertz(THz) transmission can be divided into passive transmission and active transmission, passive transmission refers to atmospheric propagation, active transmission means not only transmission but also completing a function, so also can be said functional transmission.Knowledge of the transmission of terahertz wave is very important for terahertz technology and its applications. We analysis detailed the atmospheric propagation model of terahertz wave, propagation effects, propagation equation, then carry out atmospheric propagation measurement system based on THz-TDS.
