Paper Abstract

Important features of high-current dielectric Cherenkov masers (DCMs) connected with their possible future development are considered theoretically. The start current problem is considered for the DCM oscillator in the intense beam (two-wave) operation regime which is inevitable for low millimeter and submillimeter ranges, when the beam-dielectric gap is comparable with the wavelength. The set of equations for start current finding has been obtained taking into account the frequency dependence of the beam-wave coupling. The calculations show that the values of start current are several times greater than ones obtained under the assumption that the beam-wave coupling is constant determined at the synchronous frequency.
