摘要：
Optically active cross polarization converter formed by V-shaped metallic resonator (VSR) shows high rate of polarization conversion efficiency in multiple frequency bands as demonstrated numerically. Importantly, VSR chiral metamaterial has shown broadband frequency regime for circularly polarized wave and near-zero ellipticity for linear EM-wave propagation. The giant optical activity in metal-dielectric composite structure arises due to the strong cross-coupling between the electric and magnetic dipoles resulting in strong rotatory power. The mechanism of cross coupling is understood based on surface current distribution on the patterned metallic inclusions.
