Embodiment Construction

[0056] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0057] see figure 1 , an embodiment of the present invention includes the following steps:

[0058] S1: According to the electromagnetic wave coupling mode equation, analyze the coupling mechanism of the four-way synthesizer, give the best mode and the best matching method; use the magnetic coupling method, analyze the influence of different input polarization modes on the coupling efficiency, and deduce the strength of the coupling degree Weak relationship with waveguide radius, microwave frequency, microwave mode and slit width, seeking four optimal polarization input methods:

Abstract

The invention provides a four-path high-power microwave synthesizer manufacturing method based on 3D printing and a synthesizer. A relationship between a coupling degree and a waveguide radius, a microwave frequency, a microwave mode and a slit width is deduced according to an electromagnetic coupling wave theory. A time domain finite difference algorithm is adopted to model the synthesizer, simulation is performed according to the coupling wave theory, and finally, the synthesizer is formed at a time through 3D printing, a four-path high-power synthesizer with high synthesis efficiency is manufactured, and a function of synthesizing microwaves output by microwave sources of multiple different frequency bands and the function of outward radiation of a common antenna are achieved. Namely, synthesis efficiency and total output power of the microwaves are improved while an output microwave frequency band of a system is expanded. The four-path high-power synthesizer is formed and manufactured at a time through a 3D printing technology, a sparking problem when the synthesizer is manufactured through a traditional method is effectively solved, and the method and the synthesizer are applied to an HPM radiation system with output power which is an MW-magnitude microwave millimeter wave source.

Description

technical field [0001] The invention belongs to the technical field of high-power microwave synthesis, and in particular relates to a manufacturing method and a synthesizer of a four-way high-power microwave synthesizer based on 3D printing. Background technique [0002] High-Power Microwave (HPM) generally refers to electromagnetic waves with a peak power greater than 10 MW and a frequency between 1 GHz and 300 GHz. High-power microwaves are widely used in directed energy devices and high-power radars. [0003] In order to obtain higher pulse power or pulse repetition frequency, it is necessary to explore and research HPM synthesis technology. If there are two HPM sources with the same working frequency band, if you want to radiate the HPM generated by the two HPM sources at the same time, you must develop two sets of matching antennas; Combining and then radiating with the same antenna greatly reduces equipment cost. This synthesis is not power synthesis in the usual se...
