Multiconductor transmission line modeling of SWCNT bundles in common-mode excitation

The multiconductor transmission line formalism is applied to the modeling of bundles of metallic and semiconducting single-walled carbon nanotubes. The developed approach accounts for the effects of electron transport at nanoscale and for the propagation of the voltages and currents along the bundle at the macroscopic level. The expressions of the matrices of the per-unit-length equivalent impedances and admittances of the bundle are derived considering the effect of wrapping and twisting of the nanotubes along the length of the bundle. Numerical calculations are performed in order to predict the current distribution among the metallic nanotubes of the bundle and the attenuation/transmission characteristics of the resulting multiconductor nano-transmission line.
