Semiclassical approach for the theoretically calculation coefficient absorption of carbons nanotubes verticals array in far infrared range

Abstract

There are some methods of calculating interaction irradiation with substances of carbon nanotubes. Choosing a calculating technique depends on wavelength range. In the middle and far range of infrared region interaction between radiation and material describes classical approximation. Mostly low frequency electric field of the electromagnetics wave influenced by free charges carriers, carbons construction nanotubes. Also some influence is observed on separate atoms, but there isn't significant. Value of electricity and optical parameters of nanotubes depend on the diameter and wrapping type of the nanotube. Another one cross plane distance between nanotubes plays a main role in appearing effective media material. Last one factor which affects the value of the absorption coefficient is nanotubes length. Relative between length of nanotubes and wavelength give interference effect, which forms a standing wave. In general we consider nanotubes long line electromagnetics systems. We calculate Maxwell's equations taking this fact into account.
