More on the Size Effects on the Optical Properties of the Metallic Nanotubes

The frequency dependencies for the diagonal components of the polarizability tensor of the metallic nanotubes have been obtained. The different approaches to the considering of the surface scattering of electrons have been analyzed. The calculations have been performed for the nanotubes Au, Ag, Cu, Al. It has been established that the location of the maximums of the polarizability and the scattering cross-section depend on the radius of the dielectric core and on the thickness of the metallic nanotube.
