%D 2024 %X Design of modular, passive, and static artificial metasurface as electromagnetic skins (EMSs) is introduced in this paper to boost wireless signals in cities. To achieve this goal, we propose a specialized design strategy that seeks optimal tradeoff solutions to ensure adequate coverage in areas with weak base station signals. The optimal EMS layout is determined using a binary multiobjective optimization method.Representative numerical results are presented and discussed to showcase the features and potential of the EMS solution within a smart electromagnetic environment (SEME), demonstrating the effectiveness of the proposed design method. %I ELEDIA Research Center - University of Trento %A Paolo ROCCA %A Pietro DA RĂ¹ %A Nicola ANSELMI %A Marco SALUCCI %A Giacomo OLIVERI %A Andrea MASSA %K Artificial materials, millimeter wave, mobile communications, multiobjective optimization, smart electromagnetic (EM) environment. %T Developing Modular Reflective EM Skins to Boost Wireless Signals in Cities %L elediasc12892
