We theoretically propose a unidirectional dual-band circular polarizer using a subwavelength hybridized metamaterial. By fulfilling the critical requirements of left-/right-handed circular polarizer design at each band, the polarization handedness filtration can be flipped in the same structure at different operation frequency band. The physics behind this exotic performance is further explained by a simple analytical model. Our investigation expands the capabilities of metamaterials in getting intriguing optical properties. The proposed metamaterial polarizer is helpful in effective and fruitful optical polarization manipulation and is highly valuable for the development of nanophotonic devices.
