PLANE-WAVE REFLECTION FROM UNIAXIAL CHIRAL INTERFACE AND ITS APPLICATION TO POLARIZATION TRANSFORMATION

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