ABSTRACT
We demonstrate optical activity in an intrinsically non-chiral anisotropic planar metamaterial. The phenomenon is due to extrinsic chirality resulting from the mutual orientation of the metamaterial structure and the incident electromagnetic wave. The polarization effect, which has a resonant nature, features a spectral band where linear birefringence is practically absent and can be easily tuned by tilting the plane of the metamaterial relative to the incident beam.

    The idea of transmission polarizers realized by anisotropic metamaterials is demonstrated by experiments. One of the polarizers converts linear-polarized waves to circular-polarized waves, while the other polarizer converts linear-polarized waves from one polarization to its cross polarization....
