Analysis of Working Mechanism of Energy Selective Surface
In recent years,the development of strong electromagnetic weapons has posed a serious threat to electronic equip-ment.Energy selective surface(ESS)is a new type of adaptive strong electromagnetic protection technology,which solves the problem of protection and compatibility for front door protection,and provides new technical ideas for strong electromagnetic protec-tion.In order to illustrate the working principle of ESS,the equivalent medium model and the transmission line model of ESS are established from the perspective of field and circuits,respectively.Based on electromagnetic theory and transmission line theory,the wave impedance transformation conditions and equivalent impedance transformation conditions of ESS have been systematically derived.Finally,an ESS based on a split-ring resonator is taken as an example to verify the proposed model,and the theoretical a-nalysis and simulation results are in good agreement.This work provides a systematic theoretical guidelines for the design of ESS and makes contributions to the further development of ESS.
