The electromagnetic field generated by a system of carbon nanotubes of variable length and radius that interacts with a charge that travels at a fast velocity above a CNT nanostructure was investigated. The simulated nanotubes are found resonating at a certain frequency ω p , an important resonance parameter that generates different levels of surface plasmons. The Finite Differences in the Time Domain method (FDTD) was applied to study a frequency range ω p where a maximum peak of plasmon-polariton energy was found with an optimal coupling between the charge and the CNTs system.
