线缆EMP耦合机理分析及其SPICE模型
Mechanism Analysis and SPICE Model for EMP Coupling to the Cable
摘要 介绍了线缆EMP 耦合SPICE 模型方法的求解过程,即把分布源等效为集总源,在线缆两端加载等效激励源进行仿真分析,从而把场线耦合问题转化为电路求解问题,并通过算例验证了该方法分析效率高、方便快捷、精度可靠。

Abstract The solving process of SPICE modeling method for EMP coupling to the cable,
which transforms the distributed sources into the equivalent lumped sources and loads
these equivalent sources at the both ends of the cable, is introduced. The method changes
the coupling problem into the circuit problem,which is effective, convenient and precise for
solving the induced voltage of the cable through verification from the simulation results.
Keywords EMP; cable; SPICE; simulation analysis
