ABSTRACT  

Terahertz (THz) waves show great potential in many scientific research and application fields, such as free space communication, environmental sensing, medical imaging, and biology detection. Besides radiation sources and detectors, THz waveguide propagation methods devices, such as modulators, filters and polarizers, are also of very importance. THz waveguides also closely related to the applications of surface plasmons (SPs), which are quasi two dimensional electromagnetic excitations bounded to the metal-dielectric interface, exhibiting subwavelength confinement. Additionally, with the merits of high carrier mobility and strong interaction with light in broad frequency regimes, Graphene has attracted considerable attention for in fundamental physics and practical applications. It can be regarded as an alternative to traditional metallic materials and serve as a good platform for SPs. For instance, graphene SPsshows strong confinement and relatively long propagation. Furthermore, its plasmonic properties can be tuned through electric field, magnetic field or chemical doping.
