Pseudo-Bianisotropic Coupling Through Coherent Illumination

One of the main advantages of bianisotropic metasurfaces is their capability to produce asymmetric scattering depending from which side they are illuminated. For most applications, these meta-surfaces are expected to be illuminated with a single source at a time. However, in applications with simultaneous illumination by two or more sources, bianisotropic effects can be replicated by exploiting coherent illumination. In this talk, we discuss how asymmetric scattering can be realized for a planar 180° hybrid junction using bianisotropic metasurfaces with omega response and non-bianisotropic metasurfaces under coherent illumination.
