A Ultra-Wideband Polarization Conversion Metasurfaces Used for RCS Reduction
2019 IEEE MTT-S International Microwave Biomedical Conference (IMBioC)（2019）
Abstract
A new kind of ultra-wideband polarization conversion metasurfaces (PCM) is proposed, the polarization conversion ratio (PCR) of the proposed PCM is more than 90% with the bandwidth from 5.6 to 17.9GHz, the relative bandwidth reaches up to 105%. Then, the PCM is arranged in a chessboard configuration. A 10dB radar cross section (RCS) reduction is achieved from 5.4 to 17.4GHz. The chessboard with PCM is fabricated and measured. The measured results are in good agreement with the simulation results.
