Reflection of a normally incident electromagnetic wave from a periodic biisotropic structure on a substrate

Problems of reflection of a plane circularly polarized electromagnetic wave incident normally on a biisotropic layer on a reflecting substrate and reflection from a planar periodic biisotropic structure on a substrate are solved. Numerical and graphical analysis of dependences of the reflection coefficients on the thicknesses of layers is performed. The obtained dependences have been found to be periodic; these periods are found analytically. Combinations of parameters of the problem are determined at which reflection coefficients for electromagnetic waves of left and right polarizations coincide.
