Abstract

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.
