Abstract
The plasmon dispersion relation of a quantum wire is derived by solving Maxwell’s equations for an anisotropic dielectric waveguide including retardation effects. In the long-wavelength limit, and for the extreme quantum limit, the group velocity of the one-dimensional electron gas is found to be finite and given by the Fermi velocity.
