Abstract:We propose and analyze a multifunctional THz device which can operate as a tunable switch and a filter. The device consists of a circular graphene nanodisk coupled to two nanoribbons oriented at 90 • to each other. The graphene elements are placed on a dielectric substrate. The nanodisk is magnetized by a DC magnetic field normal to its plane. The physical principle of the device is based on the propagation of surface plasmon-polariton waves in the graphene nanoribbons and excitation of dipole modes in the nan… Show more
