Reconstruction of the coordinate dependence of the diagonal form of the dielectric permittivity tensor of a one-dimensionally inhomogeneous medium

Abstract

We demonstrate the possibility of a unique reconstruction of the coordinate dependence of all dielectric permittivity tensor components of an absorbing one-dimensionally inhomogeneous plate with any symmetry (except for 1, 2, and m classes) and a negligibly small spatial dispersion. This reconstruction can be performed, the zone of the strong frequency dispersion of the medium inclusive, provided that the reflection and transmission coefficients for the p- and s-polarized plane monochromatic waves are known in a certain range of incidence angles.
