摘要 通过数值计算,研究了快上升沿电磁脉冲信号在有界波模拟器中的传输特性.采用矩量法(MoM)结合快速多极子(FMM)方法,对模拟器在传输不同上升沿电磁脉冲信号时内部的电场波形分别进行了计算.理论分析了有界波模拟器的频率特性,确定了该模拟器所能模拟电磁脉冲上升沿的上限,其结论对设计上升沿2~3 ns的大型电磁脉冲场模拟设备具有一定的参考意义. This paper studies transmission characteristic of fast rising time EMP ( electromagnetic pulse) signal in bounded - wave simulator by using numerical calculation. Electric field in bounded - wave simulator excited by different rising time EMP is calculated using the method of moment ( MoM ) and fast muhipole method (FMM). The result illuminates the frequency characteristic and determines the upper hmit rising time of EMP simulated by bounded - wave simulator. The conclusion has some reference meaning for developing large - scale EMP simulator with 2 - 3 ns rising time.
