Problem statement. The study of the reflection of electromagnetic waves from inhomogeneous and non-interchangeable layers of chiral metamaterials located on optically dense media, taking into account the dispersion of material parameters, is of considerable scientific and practical interest in the context of the development of modern photonic technologies and metamaterials.

Goal. Solving the electrodynamic problem of reflecting a horizontally polarized electromagnetic wave from an inhomogeneous chiral metamaterial located on an optically dense medium, taking into account the dispersion of material parameters.

Results. It is established that the non-reciprocity parameter does not significantly affect the reflection level of the main wave, but significantly affects the reflection level of the cross-polarized wave. The maximum value of the reflection coefficient is observed in a mutual medium, and an increase in the non-reciprocity parameter leads to a decrease in this value due to the non-synchronous interaction between the polarized components of the wave and the medium.

Practical significance. A two-point boundary value problem has been solved using the differential run method, which makes it possible to obtain analytical expressions for the reflection coefficients of the main and cross-polarized components of the field. The study includes an analysis of the frequency characteristics of reflected waves under various conditions of non-reciprocity and heterogeneity, including for homogeneous and parabolic layers.
