Engineering of Intelligent Reflecting Surfaces: Reflection Locality and Angular Stability
Reconfigurable intelligent surfaces (RISs) are electromagnetically passive controllable structures, deflecting incident wave beams in tunable directions. A usual way to design RIS using metasurfaces (MSs) is based on the approximation in which the reflective properties of a uniform MS are attributed to unit cells of the nonuniform one. We call …
