By assuming the metallic double-walled carbon nanotubes as two coaxial free electron gas layers with linearized hydrodynamic model, it is shown that surface plasmons coupled with electromagnetic fields can be excited on a metallic double-walled carbon nanotube and propagate along its axis. Dispersion relations of surface plasmons for E-type and B-type waves in various inner-outer radii and various interlayer distances for long metallic double-walled carbon nanotubes are obtained.
