Abstract

Plane-wave reflection and transmission in a planar interface between air and an axially chiral uniaxial medium whose axis is parallel to the interface is considered in the present study. By finding the reflection dyadic and its eigensolutions, we demonstrate that by dimensioning the uniaxial medium in a proper way, it is possible to make a reflection-transforming reflecting surface. The surface is able to transform the incident linear polarization into any other polarization with chosen axial ratio and handedness, and the reflected polarization can be continuously adjusted by rotating the surface around its normal direction. The reflected power is seen to be independent of the polarization of the reflected wave
