In this paper we present the theoretical considerations and the design evolution of a proof-of-concept intelligent metasurface, which can be used as a tunable microwave absorber, as well as a wavefront manipulation and polarization conversion device in reflection. We outline the design evolution and all considerations taken into account, from the selection of patch shape, unit cell size, and substrate, to the topology of the structure that realizes the desired tunability. The presented design… Expand
