A surface Bare polarization converter vias designed and fabricated. The structure conTerts the polarization of surface waves between pare TM and IE polarizations. The design was fabricated using printed circuit techniques, and it was composed of a solid ground plane and an etched top later of anisotropic metallic patterning Conversion is achieved by exciting hybrid TM-TE modes, which are different from the hybrid TM-like and TE-like modes that have been previously studied. Simulation shows conversion between TM and TE modes better than 99% while measured results show approximately 95% conversion
