A Multihop Strategy for the Planning of EM Skins in a Smart Electromagnetic Environment
IEEE Transactions on Antennas and Propagation(2023)
摘要
This article deals with the electromagnetic (EM) planning of static and passive EM skins (EMSs) in complex urban scenarios to improve the EM coverage of the base-station (BTS) antenna by means of a set of multihop (MH) cascaded reflections. Toward this end, an innovative system-by-design (SbD)-based method is developed where wireless links of arbitrary “depth,” which are implemented through multiple anomalous cascaded reflections, are optimized. Representative numerical results, concerned with real-world scenarios, are analyzed to assess the capabilities and the potentialities of such an instance of the so- called smart EM environment (SEME).
