Plasmon dispersion in metallic carbon nanotubes in the presence of low-frequency electromagnetic radiation

We present theoretical analysis of plasmon dispersion in two-walled metallic carbon nanotubes in the presence of low-frequency electromagnetic radiation, based on classical electrodynamic formulations and linearized hydrodynamic model of carbon valence electrons. Calculations are performed for the transverse magnetic and transverse electric waves, respectively, by solving Maxwell and hydrodynamic equations with appropriate boundary conditions.
