Chiral Photonic and Plasmonic Structures
Abstract
We discuss the wave propagation inside a chiral metallic/plasmonic medium defined by stacking and twisting an anisotropic medium in one direction. An anisotropic transfer matrix method for calculating the band structures and transmission properties of such a medium is described. The optical properties of some dielectric media that have the same kind of chiral structures are also discussed. When a bulk plasma dielectric function is introduced to one of the axis of the anisotropic medium, a W-shape band appears above the plasmonic bandgap. Such a chiral metallic/plasmonic medium supports both positive and negative refraction, and the criteria for achieving a negative refraction is addressed.
