A specialized design strategy is introduced to find optimal trade-off solutions that ensure sufficient coverage in areas with weak base station signals. The optimal EMS layout is achieved through a binary multi-objective optimization method. Representative numerical results are provided and discussed to showcase the features and potential of the EMS solution in a smart electromagnetic environment (SEME) and to demonstrate the effectiveness of the proposed design approach.} }
