Поверхностные Плазмон-Поляритоны В Тонкой Пленке "Графен-Полупроводник-Графен"

Abstract

In this work for far-infrared range we investigated the dispersion properties of surface plasmon polaritons in a structure «graphene plate-thin semiconductor film graphene plate». It is shown the ability of control the propagation modes by changing the chemical potential on one or both plates. It were received the dispersion relations for waves with TE- and TM-polarization and the distribution of wave field and energy fluxes along the transverse axes relate to propagation wave. It is shown that there is the spectral range, which characterized by negative group velocity.
