Abstract
In this article, we design and simulate an ultrathin wide band cross polarization conversion (CPC) Metasurface in Reflection Mode. The proposed Metasurface unit cell is made up of two split ring resonator copper patches, printed on Roger 5870 substrate back cover by a copper sheet. Over a wide frequency range of 12.5 GHz to 30 GHz, the proposed Metasurface turns a TE polarized wave into a TM polarized wave and vice versa. An efficient CPC, for both normal and oblique incidence, is achieved with 3 dB fractional bandwidth of 82.35 % from 12.8 GHz to 30 GHz (17.15 GHz bandwidth). The design Metasurface provides similar response for both TE and TM Polarized EM waves and is insensitive to incident angle due to their sub-wavelength size, unique, and electrically small substrate thickness (up to 60 0 ).
