Abstract

Reflection of light from gyrotropic uniaxial film with arbitrary axis orientation accounting or repeated reflections is investigated. This problem is considered by using the covariant method for an oblique incidence of light, for different refractive indices of ambient and substrate and it is solved numerically. As a result diagonal and off-diagonal components of the reflectance matrice are calculated. Dependences of the reflection coefficients as a function of the orientation of the optical axis and gyration tenser components are discussed. The gyrotropy manifestation in anisotropic films such as changing the symmetry of the system, appearance of off-diagonal reflection coefficients in symmetrical optical orientations are shown. Such characteristic dependences makes possible the experimental determination of gyrotropy with reflected light by using ellipsometric measurements.
