Abstract
In this work, a novel broadband polarization conversion metasurface (PCM) with high polarization conversion ratio is presented for radar cross section (RCS) reduction. The reflection phase difference of the PCM unit cell and its mirror is about 180°in a broad frequency band. Based on the phase cancellation and diffuse reflection theory, a broadband RCS reduction is achieved by designing the layout of the unit cells of the metasurface. The simulation results show that the proposed metasurface can significantly reduce the RCS more than 10 dB from 7 GHz to 20 GHz (i.e., fractional bandwidth 96.3%) comparing with the same size bare metal plate. The proposed metasurface with low profile and simple structure shows great potential applications in stealth technology.
