计算金属薄膜上电磁脉冲时域透射场的近似方法

An approximate method for calculating the time domain transmission through the thin metal shields

提出了一种计算金属薄膜时域透射系数的新方法 ,该方法用奇点展开法 (SEM)和高频渐近 ,将时域透射系数表示为不同的两个级数 ,这两个级数对早时响应和中时、晚时响应的收敛速度不同 .对早时响应采用高频渐近 ,而对中时、晚时响应采用SEM计算 .

This paper develops a novel method in time domain for calculating the transmission coefficient in which thin metal shields are driven by arbitrary EMP, using the singular expand method (SEM) and the high frequency asymptotic theory for different frerquencies for that coefficient. Some typical calculations are given.
