Abstract

Parallelized finite-difference time-domain(FDTD) method for simulating the bounded wave electromagnetic pulse (EMP) simulator with lumped terminator and parallel plate is presented. The effects of several model-parameters of simulator to the electric fields in the working volume are simulated and analyzed. The results show that (1) if the width of below PEC plate is (or is bigger than) 1.5 times as that of upper plate of working volume, the projection length of front transitional section does not have a significant effect on the rise-times of electric fields at the points near the front transitional section, and the rise-times of electric fields at the points near the working volume center decrease as the projection length increases, but the decrease of rise-time reduces. (2) if the projection length of the front transitional section's fixed, the fast rise-times of electric fields in working volume can't be got by increasing or decreasing the height of simulator as possible. if the projection length is 31.68m, the optimal height of simulator is 11.2m.

集总终端大平板有界波EMP模拟器的并行仿真

提出了具有集总终端和平行板的有界波电磁脉冲模拟器的并行时域有限差分(FDTD)模拟方法。仿真分析了仿真器的几个模型参数对工作体积内电场的影响。结果表明:(1)当下电浆板宽度等于(或大于)工作体积上板宽度的1.5倍时，前过渡段投影长度对前过渡段附近各点电场上升次数影响不显著，且随着投影长度的增加，工作体积中心附近各点电场上升次数减小，但上升时间减小。(2)在前过渡段投影长度一定的情况下，不能通过尽可能增加或降低模拟器高度来获得工作体积内电场的快速上升次数。投影长度为31.68m时，模拟器的最佳高度为11.2m。
