摘要
本文给出组成关系的E、B表示,导出运动介质中的波动方程及场量E、H纵分量满足的方程。对于电磁波垂直入射于相向运动的等离子体介质表面,求得了反射波、透射波以及透射波的色散关系和频率关系,讨论了透射波的截止和反向及频率移动。对于脉冲波,演算得到反射脉冲脉宽压缩和脉冲放大。
The E,B representation of constitutive relations are given, the wave equation in moving medium and the equations which the longitudinal components of field quantities E,H satisfied are derived. For electromagnetic wave normally incident in an oncoming plasma half space,the wave reflection and transmission are solved,the dispersion relation and frequency relation of transmission wave are obtained,its frequency shift,wave cutoff and propagation reversion are discussed.For a pulse wave inczident,the reflected pulse compression and pulse amplification are calculated.
