Abstract
Plasma waves which propagate in a pair of parallel metallic
carbon nanotubes are studied within the framework of the classical
electrodynamics. Electronic excitations over the each nanotube
surface are modeled by an infinitesimally thin layer of
free-electron gas which is described by means of the linearized
hydrodynamic theory. An explicit form of plasmons dispersion in
terms of interaction between the bare plasmon modes of the
individual surfaces of the nanotubes is presented in this Letter.
