▎ 摘　　要

The tunneling of surface plasmon waves between two slabs of dielectric prisms superposed on the metal surface is studied. The prism with the incident surface plasmon wave is superposed by a stack of graphene sheets. The analytical theory is built to connect the Fermi energy of graphene with the Goos-Hanchen shift of the transmitted surface plasmon waves. The obtained results may be useful for developing integral switching devices on the basis of surface plasmon polaritons.
