The use of tunable metasurfaces for engineering and optimizing propagation environment is actively considered by the telecommunications community. These metasurfaces serve as anomalous reflectors that redirect incident waves into the desired direction. Known models of anomalous reflectors assume that each metasurface element (meta-atom) acts as an independent relay, reflecting the incident waves with a desired phase shift, realizing the phased-array functionality. This assumption, however, is not valid for vast majority of anomalously reflecting metasurfaces. Moreover, the known theories of metasurface reflectors is limited to infinite planar reflectors. In this talk, we will present an approximate analytical model of far-field scattering from anomalously reflecting metasurfaces of a finite size and discuss the features of reflected fields that cannot be found using the known models.
