Abstract: Spherical metasurfaces are particularly suited for the beam forming as they intrinsically cover the entire radiation space. We introduce here the possibility to realize multiple simultaneous and independent beam forming operations with a metasurface synthesized by Generalized Sheet Transition Conditions (GSTCs) combined with bianisotropic surface susceptibility tensors. Specifically, we demonstrate a spherical metasurface tilting upwards and downwards the radiation patterns of an electric dipole and a magnetic dipole, respectively.
