Resonant Nonlinear Scattering of Terahertz Waves on the Periodic System of Graphene Strips

The resonant nonlinear scattering of terahertz electromagnetic waves by the dielectric structure with a periodic system of graphene strips is investigated theoretically. The strong electron graphene nonlinearity and the electron dissipation are taken into account. The nonlinear electron dynamics is considered within the pseudo-relativistic hydrodynamic equation. The effective matrix algorithm jointly with the iteration procedure for the nonlinearity has been applied. This structure has a high quality factor. The resonant nonlinear switching of the reflection and transmission occurs in this system.
