Nonlinear Metasurface Antenna Radome for Power Protection Application

In this paper, the nonlinear metasurface based on the one-layer split ring resonator array placed on a kind of elastic superstrate is discussed. Its band stopping frequency band can be shifted under incident EM waves with increased powers. The application for power protection of antenna is proposed based on the designed nonlinear metasurface radome, and the experimental demonstration is schematically provided.
