Signal-to-noise ratio between coupled carbon nanotube dipole antennas

A method of moment procedure for accurately calculating the coupling between two carbon nanotubes dipole antennas is presented. A mixed potential integral equation is used to model the current distribution on a carbon nanotube by representing it as a nano thin-wire antenna. A quantum conductance model was used for the surface impedance. Once the current distribution has been determined, the antenna characteristics can then be evaluated. Using this methodology, the required input power for a carbon nanotube dipole antenna communication system can be calculated for various receive noise figures, bandwidths, and distances between dipoles.
