Abstract

The peak-value distribution of electric fields in testing area in " Spring-Thunder" bounded-wave electromagnetic pulse (EMP) simulator based on parallel finite-difference time-domain (FDTD) method on Message Passing Interface (MPI) platform is given. The experiment results are also presented. The field uniformity in "Spring-Thunder" bounded-wave EMP simulator is quantitatively analyzed. The mean value, standard deviation, and the field uniformity of the simulation and the experiment results are got. Both of the field uniformity agree well. It’s useful for the selection of the size and the location of the equipment under test (EUT) in the simulator in experiment.

“春雷”有界波EMP模拟器场均匀性定量分析
给出了在消息传递接口(MPI)平台上基于并行时域有限差分(FDTD)方法的“春雷”有界波电磁脉冲(EMP)模拟器测试区的电场峰值分布。并给出了实验结果。定量分析了“春雷”有界波电磁脉冲模拟器的场均匀性。得到了仿真结果和实验结果的均值、标准差和场均匀性。两者的场均匀性较好。这对实验中模拟器中待测设备的尺寸和位置的选择有一定的指导意义。
