One of the problems in the field of physics and engineering of millimeter and submillimeter wave ranges is the creation of high-efficiency sources of electromagnetic oscillations and element base of radiosystems. Significant success in this direction was achieved by transforming surface electromagnetic waves from various sources into volume waves with the help of special open electrodynamic systems. Within the field of electronics of extremely high frequencies (EHF) the transformation of electron beam (EB) surface waves into volume waves is realized by using the radiation effects, of which diffraction radiation, Cerenkov and transitional radiation have been widely used. In particular a new class of devices-diffraction radiation generators (DRG)-has been proposed and realized using the effect of diffraction radiation (DR), the EB surface waves in these devices being transformed on the periodic stucture into volume waves radiated into the open resonator or open waveguide.
