Research on Attenuation Effects of Plasma to Electromagnetic Waves and Influences to the Spacecraft Communication

Abstract

Electromagnetic waves will be attenuation when through plasma because of absorption and refraction efferts. Active application of plasma attenuation effect has good application prospect, such as aircraft stealth. But at the same time, the attenuation effect oneself will also bring some problems. For exzample, as the power system of the spacecraft, electric thruster plasma jet is possiblly to cause some problem on the communication between spacecraft and ground stations [1] .
