Smart EM Environments Planning - Concepts, Advances, and Trends

Within the Smart Electromagnetic Environment (SEME) framework, the planning of electromagnetic skins (EMSs) in both outdoor and indoor wireless scenarios is addressed to restore/enhance the received power in a given region-of-interest (RoI). Towards this end, a customization of the System-by-Design (SbD) is developed in order to solve the arising SEME optimal planning problem exploiting either single-hop (SH) or multi-hop (MH) links between the base-station (BTS) or router/access point (AP) and the RoI. Two illustrative numerical examples are reported to demonstrate the effectiveness and potentialities of the proposed planning strategies in real-world scenarios.
