不同电磁脉冲对细导线的耦合
-
摘要: 采用时域有限差分法，结合细线处理方法，分别对超宽带电磁脉冲、快前沿电磁脉冲和核电磁脉冲在自由空间细导线上耦合的电流进行了数值计算，得出了不同前沿和脉宽的电磁脉冲在细导线上的感应电流。Abstract: When scattering object is a thin wire, especially with its radius much smaller than space cell of FDTD, the combination of the method of inductance in-cell with FDTD is useful to deal with the EMP coupling to wire. In this paper we calculate the three kind of EMP(UWB、FREMP、NEMP)coupling to thin wire by it, and the induced currents in the midpoint of wires are attained.
