Guided dispersion characteristics of metallic single-wall carbon nanotubes

In the linearized hydrodynamic model metallic single-wall carbon nanotubes (SWCNTs) are assumed to be free electron gas layers. By considering the friction force due to the interaction of surface plasmon waves propagating along the metallic SWCNTs and graphite lattice we generalized the results on calculating the dispersion relation of SWCNTs with linearized hydrodynamic model. We obtained a more accurate dispersion relation and investigated the friction force dependence of dispersion relations for transverse magnetic and transverse electric propagations of two azimuthal modes.
