Fine structure of the diffraction radiation of the electron beam which is modulated by incident on lamellar grating electromagnetic wave

The creation of diffraction radiation oscillator (DRO) type devices is concerned with the search for novel regimes and excitation conditions of diffraction radiation (DR) electromagnetic oscillations in open electrodynamic structures. The actuality here is the study of radiation directional diagram (DD) changes and other DR features when static and dynamic electron beam parameters are varied (DR fine structure). It is topical, for DROs, to study the radiation fine structure of the electron beam (EB) which interacts with a DRO open resonator field. The dominant task here is the determination of the fine structure of the radiation DD of an EB, incident on a reflecting grating, that interacts with the electromagnetic field.
