Metasurface Reflective-Mode Linear and Circular Polarization Converter for C, X and Ku Microwave Applications

In this study, metasurface-based polarization converter is proposed for microwave C, X and Ku band applications. The proposed polarization converter achieve polarization conversion both linear polarization to linear polarization (LP-LP) and linear polarization to circular polarization (LP-CP) in reflection mode. The proposed polarization converter provides a right-handed circular polarization conversion (LP-CP) for y polarized incident wave in the C and Ku bands at the bandwidths of 7.9 - 7.96 GHz and 12.84 - 13.16 GHz, respectively. In addition, the proposed design performs efficient linear polarization (LP-LP) conversion with over %97 PCR in the X band at 8.68 - 11.48 GHz bandwidth.
