A Novel Cross-Slot Frequency Selective Metasurface

In this paper, a novel cross-slot metasurface with frequency selective characteristic is discussed and prepared. Based on the mirror procedure of magnetic dipoles, the metasurface can realize the decrease of the reflection energy intensity in resonant frequency band. The simulation and measurements show that the reflection energy intensity of the metasurface in the frequency range of 4.1GHz-5.6GHz is about 10dB lower than that of the metal plate in the case of vertical or horizontal polarized waves in vertical incidence, RCS has also decreased by 10dB.
