Highly tunable optical activity in planar achiral terahertz metamaterials
Using terahertz time domain spectroscopy (THz-TDS) we demonstrate tunable polarization rotation and circular dichroism in intrinsically non-chiral planar terahertz metamaterials without twofold rotational symmetry. The observed effect is due to extrinsic chirality arising from the mutual orientation...
