КОЭФФИЦИЕНТЫ ОТРАЖЕНИЯ И ПРОХОЖДЕНИЯ ЭЛЕКТРОМАГНИТНЫХ ВОЛН ЧЕРЕЗ СЛОИСТУЮ СРЕДУ ГРАФЕНА И ТОПОЛОГИЧЕСКОГО ИЗОЛЯТОРА

A comprehensive study is conducted of the optical properties of the multilayer structure of alternating layers of graphene, topological insulator, and insulator. Reflection, transmission and absorption coefficients of electromagnetic waves are analyzed for different approximations ​​of the surface conductivity of graphene and topological insulator. Investigations are conducted within the matrix optics, in which the generalized Fresnel formula for reflection, transmission and absorption coefficients are obtained. Graphene and topological insulator are modeled as infinitely thin conductive layers, which modify the boundary conditions between the dielectric media. Keywords: Graphene, topological insulator, matrix optics, reflection, transition and absorption coefficients.
