A planar metamolecule with twofold rotational symmetry that shows giant cross polarization transmission leads to strong optical activity and behaves as a perfect circular polarizer. Such planar meta­surfaces would be used to design active polarization control devices and high efficiency wave deflector by carefully engineering the phase discontinuities for real applications in optical and terahertz technologies.
