I. Introduction
The non-conventional material for the plasmon resonators, the wave propagation systems which have the nanometric dimension, the tip scanning tunnel microscopes (cantilevers), the field-effect transistors, the polarizers, the terahertz detectors, the dipole antennas and the microresonators is the single-wall carbon nanotubes (CNT) with the metallic conduction and the different geometry of the cross section [1]-[6]. From one hand, CNT are the microscopic quantum systems, the surface plasmons in which are strongly decelerated, that allows to meet the demand of the compactness, from the other hand, the damping parameter of such plasmons is the ratio of the electron collision frequency to the plasma oscillation frequency. This fact and the fact that the momentum relaxation time of the electron in CNT τ<1 ps, allow to develop the CNT based microsized terahertz resonators, the Q-value of which is acceptable.
