Diffraction Theory to Model Metasurfaces in Real-World Environments

It is expected that future mobile communication systems will exploit the possibilities of intelligent radio environments to enable the controllability, programmability, and optimization of the propagation channel. This technology will need reconfigurable and smart metasurfaces integrated into walls, ceilings, or facades. One challenge to be solved for development of this technology is to create a modelling tool for finite-sized metasurface panels that can be integrated into the models of the propagation channel. In this work, we study how to analytically characterize the far-field scattering properties of reflective metasurfaces mounted on a wall.
