Abstract

The invention provides a composite ceramic gyromagnetic nonlinear transmission line. The whole composite ceramic gyromagnetic nonlinear transmission line is of a multi-layer coaxial cylindrical structure, is sequentially provided with a coaxial inner conductor, a ferrite magnetic ring layer, an insulating medium layer, a coaxial outer conductor, a coil and an oil gas charging nozzle from the axis to the outside, and further comprises an inner ceramic layer laid on the outer wall of the coaxial inner conductor and / or an outer ceramic layer laid on the inner wall of the coaxial outer conductor. According to the composite ceramic gyromagnetic nonlinear transmission line provided by the invention, the inner ceramic layer and the outer ceramic layer are respectively laid on the outer side of the coaxial inner conductor and the inner side of the coaxial outer conductor, so that the structure of the gyromagnetic nonlinear transmission line is optimized, and the insulating strength between the coaxial inner conductor and the coaxial outer conductor is enhanced, and therefore, broadband electromagnetic pulses with higher power can be output; and the technical defect that local breakdown easily occurs between the inner conductor and the outer conductor of the gyromagnetic nonlinear transmission line in the prior art, so that the improvement of the power capacity of the gyromagnetic nonlinear transmission line is restricted is effectively overcome.

Description

technical field [0001] The invention relates to the field of broadband high-power microwaves, in particular to a composite ceramic type gyromagnetic nonlinear transmission line. Background technique [0002] At present, high-power radio frequency electromagnetic pulses have extensive and extremely important applications in many fields such as space satellite communication, high-energy electron beam generation, high-power microwave radiation and propulsion. The nonlinear transmission line is a solid-state modulation device that can generate broadband radio frequency electromagnetic pulses. Because it gets rid of the need for vacuum electron beams and pinching strong magnetic fields, and does not require a gas spark switch as an oscillation element, the repetition rate operation capability It can reach above the kHz level, and the oscillation frequency of the modulated pulse can also be adjusted. In the prior art, there are mainly two types of nonlinear transmission lines tha...
