The possibility of passive flat patterned electromagnetic skins (EMSs) to support point-to-point fixed wireless access links that surpass the asymptotic free-space limit of total path attenuation (TPA) is discussed in this work. The design methodologies, technological challenges, and potential applicative scenarios of the proposed solutions are reviewed. Some proof-of-concept results are discussed to point out the feasibility of the proposed solution strategy in realistic scenarios.
