- Abstract
In this paper an efficient means to control the reflection and transmission characteristics of wire-based frequency-selective surfaces (FSS) using linear-lumped impedance loading is presented. We show that by varying the topology of the RLC loading circuits and the component values it is possible to control the resonance frequency of the array as well as its angular characteristics. We discuss several examples, particularly a switchable dual band bandpass filter and enhancement of FSS angle-of-arrival properties. The analysis is based on the self-consistent solution of thin wire Hallen's type integral equation solved by Galerkin's method. The periodic Green's function in the kernel of integral equation has been accelerated using the Ewald transformation, which leads to a highly accurate and efficient numerical procedure.
