%X One of the topical problems of modern radiophysics is the study of fundamental properties of the solid-state structures that contain nanodimension fragments. Studies of the excitation mechanisms of electromagnetic waves when the charged particles move in various electrodynamic systems form the basis of electronics. In this case, a number of the fundamentally important characteristics of the structures includes their dispersion equations. They make it possible to determine the place of electrodynamic structures in the radiophysical systems of different purposes. An energy loss of a charged particle per unit time on the wave and/or oscillation excitation in the system is the data characteristic. The dispersion equations characterizing the eigen modes of a semiconductor (or dielectric) cylinder with a layer of 2D electron gas on a side surface thereof have been obtained in an electrostatic approximation and the energy loss of the charged particle has been determined when it is moving along a spiral path around such a structure. The dispersion dependences of eigen slow waves of the system have been obtained, and the energy loss of the particle moving in an external magnetic field with the electric-field vector directed parallel to the longitudinal axis of cylindrical structure symmetry have been found. The features of the gyrosynchrotron resonance of system (of the Doppler effect) are determined. The structures of both the plasma layer and without it are studied when their eigen frequencies are in the terahertz range. A comparison of the spectra of eigenfrequencies of the systems is made. The influence of a surface nanodimension plasma layer on the eigen frequencies of semiconductor and dielectric cylinders is studied. The results of the investigation extend our conceptions about the electrodynamic properties of systems with plasma-like mediums and systematize the knowledge of the excitation mechanisms of electromagnetic waves in electrodynamic systems that form the basis of microwave devices.
