Study of the Angular Spectrum of a Bianisotropic Refractive Metasurface at a Dielectric Interface

We present an initial study of the angular spectrum of a bianisotropic refractive metasurface at an interface between two dielectric media. In this study, we report on the existence of three distinct angular regions: a) a rotated transmission cone, b) a modified total internal reflection region, and c) a new total retro-reflection region.
