Analysis on the Reflection Characteristic of Electromagnetic Wave Incidence in Closed Non-Magnetized Plasma

Abstract

The reflection characteristic of EM-wave (Electromagnetic Wave) incidence in non-magnetized closed plasma with uniformed multi-layer and outer envelope is discussed accordingly to plasma stealth technology applying practically to aircrafts. Based on wave impedance matching principle, the reflection coefficient of the composed structure including outer envelope dielectric and plasma plus metal plate is deduced and completed. Furthermore, the reflection loss is also yielded when double-pass attenuation is concerned. The reflection loss varying pinciples are given by adopting numerical method as EM-wave incidence angle and plasma temperature vary in the case of different plasma electronic density profiles, which provides a certain reference to plasma stealth technology applied to aircrafts and missiles.
