A general technique for THz modeling of vertically aligned CNT arrays

In this paper a general technique for the simulation of the single- and multi-wall carbon nanotubes is proposed based on a multi-conductor transmission line (MTL) model. The analytical form of the 2-port S-parameter is calculated from the 2n-port transfer matrix of the CNT array, which takes the mutual couplings of CNTs into consideration. The result is compared with that of previously used models. The simulated input impedance and absorption provides information of CNTs for potential THz applications.
