Numerical study of polarization‐dependent focusing for a bilayer planar FSS reflective lens at millimeter wavelengths

Abstract

In this paper, we numerically analyze the polarization‐dependent focusing properties of a planar reflective lens formed by two parallel layers of nonuniform “gangbuster” surfaces (GSs) above a ground plane. Since these GSs consist of superdense arrays of thin finite‐length parallel metallic wires, the desired phase patterns on such a lens surface are achieved by adjusting the lengths of these metallic wires for appropriate polarization components. In our analysis, we use the method of moments (MoM) and the transmission‐lines analogy, along with the surface‐equivalence theorem, to estimate the field intensity in the focal plane. © 2004 Wiley Periodicals, Inc.
