Reciprocal circular-polarization-selective surface

Abstract

This paper presents the concept of an electromagnetic surface called the circular-polarization-selective surface (CPSS). Few papers have dealt with the CPSS, and it has even been argued that the ideal CPSS belongs to the category of impossible polarizers. We present herein a theoretical proof for the existence of the ideal CPSS, review the prior art in this area, identify some geometrical constraints inherent to such a device, and present the results of numerical computations.
