Scattering cross section of metallic two-walled carbon nanotubes

The electromagnetic wave scattering from a metallic two-walled carbon nanotube is studied. The system is assumed to be illuminated by either a transverse magnetic or a transverse electric wave. Boundary-value method is used to evaluate the scattering characteristics of the system. Electronic excitations of each wall of nanotube are modeled as an infinitesimally thin cylindrical layer of the free-electron gas described previously by means of the linearized fluid theory. The computed results include the evaluation of the normalized scattering width of both transverse magnetic and transverse electric uniform plane wave by system at normal incidences. ► The electromagnetic wave scattering from the two-walled carbon nanotube is studied. ► Both polarizations of the incident TM and TE waves are treated. ► General expressions for the scattered power of system are obtained. ► For both modes the scattered power can be significantly enhanced by increasing the number of walls.
