Resumen

[EN] The use of reconfigurable intelligent surfaces (RISs) foroptimization of propagation channels is one of the most promising and revolutionizing techniques for improving efficiency of the next generation of communications systems. In this article, we combine physical optics approximation and the theory of diffraction gratings to study the scattering properties of finite-size metasurfaces mounted on partially reflecting walls. We consider both reflective and refractive metasurfaces designed to control both the reflection and transmission of waves. We start the analysis under the assumption of uniform, plane-wave illumination, and then discuss nonuniform illuminations by directive antennas.
