Reciprocal circular polarization selective surfaces

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.
