Dispersion of Surface Waves at the Interface between a Dielectric and a Finely Layered Ferrite–Graphene Medium

Abstract

The propagation of guided ТМ- and ТЕ-polarized waves along the interface between a dielectric and a finely layered ferrite–graphene plasmon-polariton medium have been investigated. Based on the long-wavelength approximation, expressions for effective permittivity and permeability of a layered medium have been derived and used to establish dispersion relations for these waves and build frequency dependences of propagation constant real and imaginary parts. Where the waves are surface or radiation have been determined.
