Field-circuit co-simulation and experiment of electromagnetic energy selective surface

In order to study the protective performance of energy selective surface(ESS), this paper uses the PIN diode Spice model to obtain the transient response waveform of ESS by field-circuit co-simulation in time domain. The parameters that affect insertion loss and protective performance are studied, and structural parameters are optimized to reduce spikes. The results show that the double ESS can effectively protect the reverse pulse, and increasing the length of the metal strip can reduce the pulse spike. In this paper, the transmission of small signals and shielding of high power electromagnetic pulse are verified by high power electromagnetic pulse irradiation experiment, which provides a reliable method for HPM protection.
