Abstract
In this presentation we will review our recent works on designs and testings of effective anomalous reflectors and beam splitters. First, we will make a comparative overview of known methods to design stationary and reconfigurable metasurfaces for shaping reflected waves. Next, we will present our recently developed approach based on optimization of step-wise homogeneous impedance sheets. We will show examples of practical designs and experimental results in the millimeter-wave band. Furthermore, we will discuss reflection and scattering from finite-size metasurfaces mounted an walls and show a possiblity to change reflections from the illuminated part of the uniform wall by engineering interference with the waves scattered by the metasurface.Description
