Electromagnetically Consistent Bounds on Information Transfer in Real-World RIS-Parametrized Wireless Channels
Albert Salmi, Ville Viikari, Philipp del Hougne
A reconfigurable intelligent surface (RIS) endows a wireless channel with programmability that can be leveraged to optimize wireless information transfer. While many works study al…
