The proposed meta-surface behaves as an excellent cross polarization converter for linear polarized wave over the relative absorption bandwidth (RAB) of 55.2% (7.89–13.91 GHz) with more than 97% efficiency. It successfully converts linearly polarized waves into circularly polarized waves in the 7.2–7.36 GHz frequency range. In addition, its polarization conversion rate (PCR) efficiency characteristics for TE and TM modes are retained across the entire X band, with a wide incidence angle up to $45^0$. The presented polarization converter has ultra-thin feature with 0.07?0 thickness. Due to its compact size, angular stability, high efficiency, simple structure and multi- functionality, this polarization converter is an important candidate for polarization manipulation and communication devices in many applications.eninfo:eu-repo/semantics/openAccessPolarization convertermetasurfacecross polarization conversionPCRX bandArticle16392893910.18185/erzifbed.12178881218544
