  We develop an rf circuit model for single walled carbon nanotubes for both dc
and capacitively contacted geometries. By modeling the nanotube as a
nano-transmission line with distributed kinetic and magnetic inductance as well
as distributed quantum and electrostatic capacitance, we calculate the complex,
frequency dependent impedance for a variety of measurement geometries. Exciting
voltage waves on the nano-transmission line is equivalent to directly exciting
the yet-to-be observed one dimensional plasmons, the low energy excitation of a
Luttinger liquid.
