Description

one

The invention relates to microwave radio engineering and can be used in super-power electronic generators of the millimeter and submillimeter wave ranges: in Compton masers, killerrons, and cyclotron autoresonance masers.

A resonator is known that is made on a segment of an irregular waveguide l.

However, the known resonator does not provide a high quality of the working oscillation, a super-powerful generator.

The purpose of the invention is to increase the quality of the working oscillation of a super-power generator.

To achieve this goal, in the proposed resonator a segment of an irregular waveguide is composed of two periodic structures connected with a violation of the periodicity of one of them relative to the other.

FIG. 1 shows a circular cross-section of the resonator; on

FIG. 2 is a cross section of a rectangular cavity (} jurma.

The resonator contains a segment of an irregular waveguide composed of two periodic structures 1 and 2, in which the depth of the periodic corrugation is much less than the wavelength (C 4 L / 4), and the periodic structures 1 and 2 are set relative to each other with a periodicity violation. Violation of periodicity is achieved by joining periodic structures 1 and 2, having different (|) basics of the corrugation in the plane of the junction (Fig. 1) or by connecting periodic structures 1 and 2 through segment 3 of the waveguide (Fig. 2), which can be regular or any weakly nonregular. real spatial structure.

The resonator works as follows. The natural frequencies of the longitudinal oscillations of the resonator are determined by the depth O / and the period of the d-periodic corrugation, the lengths of the periodic structures 1 and 2, and the length of the segment 3. In the case when the periodic structures 1 and 2 have the same length, and in the junction planes with the segment 3 corrugations of periodic structure 1 are protruded to corrugations of periodic structure 2, the eigenfrequencies of the resonator are equal, - 4 f1 „–K -„ 1 (ni, 2,3 ...), the critical frequency is not where the cross-section waveguide; -coefficient depending on the length of the periodic structures 1 and 2 and the length of the water and parameters (i and C; C is the speed of light. As the working oscillation of the generator, the oscillation is used at the frequency LUo, which is central to the frequencies iJij The periodic structures 1 and 2 of the cavity function as reflectors,.
