[0002] High-power microwave refers to coherent electromagnetic radiation with a peak power greater than 100mw and a frequency between 1GHz and 300GHz. Its generation mechanism is as follows: after the power supply performs primary energy storage, it charges the pulse power system. After compression by the pulse power system, it generates DC pulses of tens to hundreds of nanoseconds, up to several MV, and hundreds of kA, which drive the cathode to generate an electron beam. Energy conversion is carried out in the beam interaction structure of the microwave source, converting the kinetic energy of the electron beam into high-power microwave radiation.

[0003] However, due to its own characteristics, a single high-power microwave has an upper limit due to the constraints of physical mechanisms and process conditions. In order to break through the limitation of the output power of a single high-power microwave, it is necessary to use a high-power microwave synthesis structure to synthesize the output of multiple high-power microwave sources, thereby greatly improving the output power.

[0004] However, the existing high-power microwave synthesis structure has the problems of low synthesis efficiency, low reliability and large space occupation. Utility Model Content

The first introduction assembly and the second introduction assembly are respectively fixedly connected to one of the cross tubes A, and the third introduction assembly and the fourth introduction assembly are respectively fixedly connected to the cross tube B.

[0007] Among them, the first introduction component includes a first circular waveguide tube and a first flange, one end of the first circular waveguide tube is fixedly connected to one of the cross tubes A, and the other end of the first circular waveguide tube is fixedly connected to the first flange, and the first flange has a plurality of first circular holes.

[0008] The second introduction component includes a second circular waveguide tube and a second flange, one end of the second circular waveguide tube is fixedly connected to one of the cross tubes A, and the other end of the second circular waveguide tube is fixedly connected to the second flange, and the second flange has a plurality of second circular holes.
