Modelling and Simulation of the Modified Equivalent Circuit of Electromagnetic Radiation Effects

Abstract:

In the complex electromagnetic environment, the cable is one of the paths through which the energy of electromagnetic interference (EMI) may couple into the electronic component and circuit in the shielding enclosure. A modified field-circuit method which combing the 2-port network theory and the mixed potential integral equation and the method of moments (MPIE-MOM) is presented to analyze the electromagnetic radiation effects of an enclosure with a cable under any form of electromagnetic interference. Taking the Gaussian pulse as an example, the electromagnetic radiation effect of the PCB in the enclosure is analyzed with the field-circuit method. The model presented in the paper is a theoretical reference for the design of the electronic equipment which working in the complex electromagnetic environment.
