A Reconfigurable Intelligent Surface (RIS) is a planar structure that is engineered to have properties that enable the dynamic control of the electromagnetic waves. In wireless communications and networks, RISs are an emerging technology for realizing programmable and reconfigurable wireless propagation environments through nearly passive and tunable signal transformations. RIS-assisted programmable wireless environments are a multidisciplinary research endeavor but are not well-understood. In this talk, we will discuss how electromagnetic-consistent and data-driven methods can be leveraged for optimizing RIS-assisted wireless communication networks.
