Dielectric Effects on Transmission Properties of Thick-screen Frequency Selective Surface

Fang Chuny

Abstract

In this paper,a thick-screen FSS with circle-hole elements is designed. Based on the moment method,its transmission properties for different thick metallic screen with and without filling dielectrics are analyzed and simulated.It can be seen from results that the thick-screen frequency selective surface without filling dielectrics has stable the center frequency and its bandwidth narrows as increasing the thickness of metallic screen. In addition,with increasing the thickness of metallic screen the center frequency drifts to the low frequency and the bandwidth is decreased.
