Numerical study of oblique incidence of terahertz wave into non-magnetized plasma

This paper is based on the theory electro-magnetic wave transmission in layered media[1]. The transmission characteristics of terahertz waves incident on nonuniform plasma at different angles are calculated and analyzed. The results show: The terahertz wave is incident at different angles, the reflection coefficient first decreases and then increases. And a very small attenuation. Terahertz wave can effectively solve the "blackout" problem as a communication carrier.
