Show affiliationsThe dispersion properties of low-frequency electromagnetic waves in metallic double-walled carbon nanotubes (DWCNTs) are investigated. We assume that metallic DWCNTs are charged due to field emission, and hence metallic nanotubes can be regarded as charged dust rods surrounded by degenerate electrons and ions. Calculations are performed for transverse magnetic (TM) and transverse electric (TE) waves, respectively, by solving Maxwell and hydrodynamic equations with appropriate boundary conditions.
