摘要
基于时变等离子体(TVP)的场方程,根据麦克斯韦方程,推导了TVP对入射电磁波的频率上移、时间衰减常数、反射系数,以及TVP的透射波和反射波电场幅值计算公式。通过实例计算分析了不同时间的新波频率、时间衰减常数和电场幅值。方法简单易行,可为TVP的应用提供一定的理论依据。
Based on the Maxwell equations and the electromagnetic field equations of TVP,the formulas of the frequency up shifting,the time damping constant,the reflecting coefficient,and the field normalization amplitude of transmission and reflection waves were derived for electromagnetic wave to TVP in this paper.The frequency,time damping constant,electric field amplitude in various time of some example were calculated.This method was easy and feasible,which could provide a theoretical basis for the applications of TVP.
