A Dielectric Filled Compact Relativistic Flyback Oscillator

Abstract

The invention discloses a dielectric filled compact type relativistic backward wave oscillator and belongs to the technical field of high-power microwave. The dielectric filled compact type relativistic backward wave oscillator is rotationally symmetrical relative to the central axis and consists of a cathode seat, a cathode, an anode outer barrel, a cut-off neck, a slow wave structure and a solenoidal field coil. The slow wave structure is a disk loaded waveguide type slow wave structure and consists of five slow wave blades, wherein the inner surface of each slow wave blade is of a rectangular structure. During dielectric filling, an original structure of the RBWO is not needed to be changed, and only dielectric materials are needed to be filled among all blades of the slow wave structure. The problem that a low-frequency relativistic backward wave oscillator is too large in size and weight can be solved, and the dielectric filled compact type relativistic backward wave oscillator has wide application prospect and important scientific research value on research of small-sized compact type relativistic backward wave oscillators, promotion of engineering application process of high-power microwave systems and expansion of the RBWO application field.
