Abstract

We analyze numerically the polarization-dependent focusing properties of a planar reflective lens that is formed by two parallel layers of the non-uniform "gangbuster surfaces (GS)" above a ground plane. Since these gangbuster surfaces consist of superdense arrays of thin finite-length parallel metallic wires, the desired phase patterns on such a lens surface are achieved by adjusting lengths of these metallic wires for appropriate polarization components. In our analysis, we use the Method of Moment (MoM) and the transmission lines analogy, along with the surface equivalence theorem, to estimate the field intensity in the focal plane.
