Digital Library of Periodicals of National Academy of Sciences of Ukraine| Zusammenfassung: | The results of the theoretical and experimental investigations of excitation of oscillations by flows of charged particles and its particles dynamics are represented at their motion as in a periodic potential and in a field of a plane electromagnetic wave and in periodically inhomogeneous medium. The special attention is given to research of non-relativistic motion. It was found conditions that under their fulfilling the maximum of radiation of nonrelativistic oscillators fall at high numbers of oscillators harmonics. Linear stage of beam instability is analytically studied, the increments of instability are determined. Nonlinear self-consistent theory of electromagnetic waves excitation by flows of the charged particles is developed. By the numerical methods are investigated linear and non-linear stage of excitation of a high-frequency wave with frequency corresponding to high number harmonics of external wave. Capability of effective excitation of harmonics by ensemble of nonrelativistic oscillators in SHF range and transformation of energy of external 10 cm of radiation to energy of ultraviolet radiation is shown experimentally. |
