To achieve this, a specialized design strategy is proposed to find optimal trade-off solutions that ensure adequate coverage in areas where the base station signal is weak. The optimal EMS layout is obtained using a binary multi-objective optimization method. Representative numerical results are presented and discussed to highlight the features and potential of the EMS solution in a smart electromagnetic environment (SEME) and to demonstrate the effectiveness of the proposed design method.}, keywords = {Artificial materials, millimeter wave, mobile communications, multiobjective optimization, smart electromagnetic (EM) environment.} }
