Modeling and application of equivalent source of electromagnetic pulse coupling effects

Combing 2-port network theory with Mixed Potentials Integral Equation and Method of Moments (MPIE-MoM), the equivalent source of electromagnetic pulse coupling effects of shielding with cables is modeled. Taking a Gaussian pulse for example, the electromagnetic sensitivity of the internal circuits is analyzed using the field-circuit method. The simulated results of the presented method tallies well with that with the commercial software in the frequency range of 0.1-7.5 GHz, which provides theory reference to the quantitative analysis of the electromagnetic pulse coupling effect and the circuit safety protection in complex electromagnetic interference irradiation environment.
