An Angularly Stable Tri-band Reflective Cross-polarization Conversion Anisotropic Metamaterial A tri-band microwave cross-polarization conversion (CPC) metasurface is designed and simulated. The metasurface consists of a split-ring-resonator (SRRs) with two splits placed within perpendicular sides of the SRR and designed on an FR4 dielectric substrate backed by a metallic ground plane. An efficient CPC, both for normal as well as for oblique incidence, is achieved. This multi-band polarization conversion results from multiple plasmonic resonances occurring at three neighboring frequencies. Owing to sub-wavelength unit cell size, thin dielectric substrate, and optimized structure of the SRR, the response of the metasurface is independent of the incidence angle of the incoming wave which makes it a potential candidate for many practical applications. introduction Control and manipulation of the polarization state of electromagnetic waves have always been ...
