Abstract

A broadband cross polarization converter (CPC), formed from a Twisted-F Shaped Chiral Metamaterial (TFSCM), having high optical activity is reported in this work. The pro- posed structure supports high polarization conversion efficiency which is demonstrated numer- ically. The enhanced optical activity is observed which exhibits the presence of cross coupling phenomena between magnetic fields and is explained on the basis of surface current distribution.
