摘要
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.
