Problems solved by technology

Traditional microwave generators are based on the cyclotron resonance of electrons in a vacuum environment, and use the resonant cavity and super-strong magnetic field to control the operating frequency. The additional systems required include vacuum pumps, superconducting magnets, and cooling systems, so the weight of the entire generator and The volume is relatively large, the cost is high, and the continuous working time is limited by the life of the microwave tube and is short

Embodiment Construction

[0020] Now in conjunction with embodiment, accompanying drawing, the present invention will be further described:

[0021] The solution of the present invention to solve the technical problem is: first, the high-power microwave generator is mainly composed of a coaxial transmission line, a solenoid (located outside the coaxial line), a nonlinear ferrite magnetic ring (two sections), dielectric materials and other parts Composition, its model diagram is as follows figure 1 shown.

[0022] The coaxial transmission line has the advantages of easy impedance design, symmetrical structure, and high cut-off frequency. Its main mode is TEM mode. Whether it can transmit high-order mode electromagnetic waves is related to the radial dimensions of the inner and outer conductors. Electromagnetic waves higher than the working frequency of the generator are cut off in the coaxial line; in addition, using a solid dielectric with a large dielectric constant such as epoxy resin can improve it...

Abstract

The invention relates to a coaxial high-power microwave generator based on a nonlinear transmission line. The generator comprises a first fixing flange, a second fixing flange, an outer conductor of the transmission line, an inner conductor of the transmission line, a front segment of a nonlinear ferrite magnet ring, a rear segment of the nonlinear ferrite magnet ring, a solenoid, a solid dielectric medium and a nylon fixation device. The front edge of input high voltage pulses is sharpened, an input pulse magnetic field is mutually coupled with the magnetic moment of a non-linear material to generate and output high-frequency microwave oscillation signals, and the generator is characterized by high repetition rate, high versatility, low using cost, convenient and safe performance and the like.

Description

technical field [0001] The invention is a high-power microwave generator which sharpens the leading edge of high-voltage pulses and couples and oscillates to output high-power microwaves. The generator has a compact structure and adjustable frequency, and can be used as a high-power microwave radiation source in the study of electromagnetic vulnerability of electronic devices. Background technique [0002] Although high-power microwave generation technology has been developed relatively maturely, traditional high-power microwave sources are mostly based on microwave tube systems, require a vacuum superconducting environment, and have a large size and short continuous working time. Therefore, it is very necessary to design a high-power microwave generator that has a long continuous working time and does not require a vacuum superconducting environment. [0003] According to the types of microwave tubes used in current high-power microwave generators, they can be divided into...
