摘要

本文讨论了正弦脉冲信号在运动有碰撞等离子体层上反射后的畸变

在一定条件下给出反射脉冲波形的解析表达式并对精确波形进行了数值计算。结果表明当信号频率ω

接近临界频率时畸变将很大

会使信号难以辨认

文中并对色散、运动速度、碰撞与反射波形畸变大小的关系进行了讨论。

Abstract

The waveform distortion of sinusoidal pulse reflected from a collision moving plasma layer is investigated. On certain conditions

analytic expressions for the reflected waveform are derived. Numerical calculations show that the waveform distortion is large as ωa close to ωc. The reflected waveform distortion effected by dispersion

moving velocity and collision frequency is discussed.
