Abstract Graphene is a unique material in the study of fundamental limits plasmonics. Apart from ultimate single-layer thickness, its carrier concentration can be tuned by chemical doping or applying an electric field. In this manner, electrodynamic properties graphene varied highly conductive to dielectric. supports strongly confined, propagating surface plasmon polaritons (SPPs) broad spectral range terahertz mid-infrared frequencies. It also possesses strong magneto-optical response and...
Abstract Transverse-electric (TE) surface plasmons (SPs) are very unusual for plasmonics phenomenon. Graphene proposes a unique possibility to observe these plasmons. Due transverse motion of carriers, TE SPs speed is usually close bulk light one. In this work we discuss conditions propagation in cylindrical graphene-based waveguides.
