Design and Simulation of an Improved Energy Selective Surface

Abstract

Energy selective surface (ESS) proposed in recent years is one of the most effective means for defending high intensity electromagnetic wave attacking. This paper presents an improved ESS structure and its systematic design method. An ESS prototype is designed and fabricated based on a given requirement. Its insertion loss is measured in an anechoic chamber, and its shielding effectiveness is tested under HPM and UWB irradiation. Measured results show that the ESS sample meets the given requirement.
