Abstract

This study proposes a stratified chiral metamaterial as a polarization rotator for terahertz regime. Combination of chiral constituent with dielectrics permits optimization of spectral filter and polarization rotation properties. The lack of suitable wave-plates for terahertz region opens the way for novel component/devices enabling polarization control. With the aid of a new class of metamaterials, the capability of the fabrication of multilayer structures for polarization rotator realization can be increased. We can generate either polarization-rotation combs or narrow rotation bands with very good and broad sideband suppression, of interest for example for data transmission or sensing purposes. © 2011 IEEE.
