标题： Scattering of surface plasmon-polaritons in a graphene multilayer photonic crystal with inhomogeneous doping

摘要： 沿掺杂石墨烯片堆栈传播的表面等离激子极化波被考虑。 这个辅助问题用于讨论：(i) 该模式在堆栈与真空之间的界面处的散射； (ii) 在电子掺杂发生突然变化的界面处的散射。 然后将这种形式主义扩展到{\it 障碍问题}。 在这个系统中，等离激子模式表现出丰富的物理现象，包括：全反射、全透射、法布里-珀罗振荡以及与光子模式的耦合。 显示英文摘要

摘要： 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-P\'erot oscillations, and coupling to photonic modes.
