Scattering of surface plasmon-polaritons in a graphene multilayer photonic crystal with inhomogeneous doping
arXiv:1604.00898 · doi:10.1103/PhysRevB.93.245425
Abstract
The propagation of a surface plasmon-polariton along a stack of doped graphene sheets is considered. This auxiliary problem is used to discuss: (i) the scattering of such a mode at an interface between the stack and the vacuum; (ii) the scattering at an interface where there is a sudden change of the electronic doping. The formalism is then extended to the {\it barrier problem}. In this system rich physics is found for the plasmonic mode, showing: total reflection, total transmission, Fabry-Pérot oscillations, and coupling to photonic modes.
