The purpose is experimental modeling (using numerical methods) physics of electromagnetic phenomena in quasi-optical systems multiply the millimeter range with periodic inhomogeneities, as well as analysis of two-stream cluster FEL-klystrons. The research methods are classical methods of modern electrodynamics and electronics, as well as methods of experimental modeling. The paper presents the analysis of the general concept of small electromagnetic phenomena in metal-dielectric systems and free-electron lasers, which lies in the experimental and numerical modeling of wave processes in periodic dielectric structures of various modifications, determining the appropriate embodiment of the studied devices for amplification and generation of electromagnetic waves in the millimeter-infrared ranges. In addition to the work carried out a qualitative analysis of two-stream active FEL-klystrons as a new class of electronic devices intended for the formation of clusters of femtosecond electromagnetic field. Proposed three new structural scheme of the FEL. Analyzed in detail multiharmonic processes in the transit section of such devices. Product Description popup.authors Алексенко Г.А. Барсук І.В.
