摘要
Reconfigurable metasurfaces (RMTSs) are in high demand for advanced applications in 5G wireless communications thanks to their intriguing ability to control the electromagnetic (EM) response dynamically. However, most efforts so far have focused on modulating only either the EM wavefront amplitude or frequency. The key issue limiting the development of current RMTSs is their burdensome optimization process. Given this gap, this paper proposes an accurate equivalent circuit model (ECM) for the scattering of a novel RMTS with independent control of amplitude and phase (AP-RMTS) by applying the Floquet modal expansion method. Based on the accurate ECM, we can easily design the EM response of the proposed AP-RMTS at different operating frequencies. This flexibility allows the proposed design to be readily applicable to fit different scenarios in 5G wireless communications.
