90 degree polarization rotator using a bilayered chiral metamaterial with giant optical activity

, 2010
A bilayered chiral metamaterial (CMM) is proposed to realize a 90 degree polarization rotator, whose giant optical activity is due to the transverse magnetic dipole coupling among the metallic wire pairs of enantiomeric patterns.
