Scattering properties of metallic carbon nanotubes in the presence of dielectric media

Abstract

Scattering properties of a metallic single-walled carbon nanotube that encapsulates a nanowire is studied within the framework of classical electrodynamics. The system is assumed to be illuminated by either a transverse magnetic (TM) or a transverse electric (TE) wave. Electronic excitations on the nanotube's surface are modeled as an infinitesimally thin cylindrical layer of the -electrons, whose dynamics are described by means of the fluid hydrodynamic theory. The problem is two-dimensional and the solution to both TM and TE uniform plane waves by the system at normal incidences is presented.

Scattering by an array of parallel metallic carbon nanotubes

“…The present paper is an extension of the previous investigations [7,[18][19][20][21][22][23][24] to study the electromagnetic scattering from an array of parallel metallic SWCNTs. The analysis begins by representing each field component by an infinite series of cylindrical harmonic functions with unknown coefficients.…”

“…Recently, a detailed derivation for the problem of scattering of a plane wave from single-and two-walled CNTs was presented. [20][21][22] More recently, Wu et al [23] obtained an analytical solution for the electromagnetic scattering from the infinite-length metallic CNT excited by an electric line source. Also, a theoretical investigation of linesource (both the electric and the magnetic) scattering by metallic multi-walled CNTs was presented in Ref.…”
