The paper analyzes, through electromagnetic simulations and actual PCB designs, the viability and performance of four different metasurface configurations, whose implementation has been carried out using standard PCB materials. Four surfaces with fixed reflection response have been used to asses the viability of the proposed schemes and materials for future controllable RIS implementations. Each one of the test designs uses a different element discretization configuration. An analysis via EM simulation and comparison with experimental results has been performed to study the influence of the cell discretization on the response of the surfaces, at 9.6 GHz. The conducted study and the obtained results may be useful for future designs and implementations of adaptive response RIS at higher frequencies. eng © 2024 IEEE Metasurfaces Reconfigurable intelligent surface Discrete phase configuration EM simulation PCB design ODS 9 Industria, innovación e infraestructura Towards Affordable RIS Devices: Electromagnetic Simulation and Implementation of Metasurfaces http://purl.org/coar/resource_type/c_c94f
