Generation of Electromagnetic Waves Based on Interaction Effects between Moving Charged Particles and Fields Excited by Them Eigenmodes of Waveguide and Resonator Structures (Review)

The paper presents an overview of the authors’ scientific works, which are further developments in the scientific directions of SHF and EHF electronics, which were first developed by scientists, particularly Professor V. P. Taranenko. The possibility of propagation of weakly decaying electromagnetic waves in super dimensional electrodynamic solid-state structures, including those containing plasma-like medium, is demonstrated. Attention is paid to excitation mechanisms of eigenwaves and eigenoscillations of such structures, which are based on the Vavilov–Cherenkov effect, anomalous Doppler effect, or transient radiation. The generation of electromagnetic radiation in the interaction between the charged particle flows, and the fields of eigenwaves or eigenoscillations of such structures have been demonstrated. The possibility of mastering the millimeter and submillimeter wavelength ranges using multimode electrodynamic structures with dimensions acceptable for production is shown. Electrodynamic systems based on supercritical currents of the relativistic electron beam, such as virtod and virtod-BWT, are presented, in which the control of the amplitude-frequency characteristics of microwave radiation is implemented.
