Surface polariton propagation in structure with a graphene layer

The paper considers the process of diffraction of an electromagnetic wave at the interface "vacuum – metal – nonlinear layer (graphene) – semiconductor" with the excitation of a surface wave. Within the framework of the theory, a modal method for calculating the process of interaction of radiation with a multilayer structure is presented, which makes it possible to calculate the energy fluxes arising in the process of diffraction.
