Study on the Absorption Characteristics of Ultra-High Frequency Microwave by Inhomogeneous Plasma

摘要

Based on the geometric model of the interaction between plasma and electromagnetic wave, the absorption attenuation formula is obtained by using the WKB approximation method. The interaction and mechanism of interaction between electromagnetic waves and plasma collision fre-quency and plasma peak density at different incident angles are discussed. The result illustrates that the wave attenuation is stronger when the plasma density presents a parabolic distribution.
