Abstract

The invention discloses a compact relativistic magnetron of an axial output structure, and belongs to the technical field of high-power microwaves. The structure comprises a ten-resonant-cavity rising-sun-shaped relativistic magnetron, a coupling structure serving as a transition structure and a ridged circular waveguide output structure. The problem that high-order mode electromagnetic waves aredifficult to use efficiently in the magnetron axial diffraction output scheme is solved, the output energy is directly and efficiently extracted from the rising-sun-shaped relativistic magnetron in aTE51 mode by using a ridged circular waveguide structure, and the efficiency can reach 70%. Meanwhile, the total volume occupation of the whole system is remarkably reduced, and by taking an L-band working state as an example, the radius of the circular waveguide is reduced to 130mm from 250mm in the existing scheme, and the axial full length is reduced to 490mm from 866mm.

Description

technical field [0001] The present invention relates to the field of high-power microwave technology, in particular to a miniaturized L-band relativistic magnetron, which is based on the extraction scheme of an axial circular waveguide with ridges, and outputs microwave energy in TE51 mode, so as to further pass through the circular waveguide on the outer wall axially. The slot array radiates energy outward. Background technique [0002] From the perspective of practical high-power microwave systems, the development of high-power microwave systems mainly focuses on four aspects: (1) Miniaturization and compactness of the system to improve power consumption ratio; (2) High repetition frequency work; (3) The frequency can be tuned; (4) Multi-frequency output. Since the birth of relativistic magnetron, it has been attracting much attention, and plans have been made to study it. The initial stage mainly focused on the research on improving the output characteristics of a single...
