Embodiment 1

[0021] see figure 1 , where a is the main view, b is the left view, and c is the top view. The microwave power confocal synthesis device in this example includes a microwave input terminal A and a microwave input terminal B, and their corresponding waveguide cavities are waveguide cavity 1 and waveguide cavity 2 respectively, and waveguide cavity 1 and waveguide cavity 2 are connected to form a confocal cavity. The side walls 10 and 20 of the waveguide cavity 1 and the waveguide cavity 2 are perpendicular to the bottom surface 11 and the top surface 12, and the orthographic projections of the side walls 10 and 20 on the bottom surface 11 and the top surface 12 are elliptical arcs, see figure 1 a. The two focal points of the waveguide cavity 1 are A and O respectively, and the two focal points of the waveguide cavity 2 are B and O respectively. The focal point O is the common focal point of the waveguide cavity 1 and the waveguide cavity 2, that is, the microwave converging e...

Embodiment 3

[0025] Such as image 3 As shown in the figure, a is the main view, b is the left view, and c is the top view. The microwave power confocal combining device in this example is composed of four waveguide cavities with the same structure, see image 3 Waveguide cavity 1, waveguide cavity 2, waveguide cavity 3 and waveguide cavity 4 in a. The side walls of the four waveguide cavities are perpendicular to the bottom surface and the bottom surface of the waveguide cavity, and the orthographic projections on the bottom surface and the bottom surface of the waveguide cavity are uniform elliptical arcs. One focus of the four waveguide cavities coincides, which is the common focus O in this example, and the other focuses of the four waveguide cavities are respectively A, B, C, and D, which are located at the endpoints of two vertical straight lines (straight line AB and straight line CD), In this example, the four microwave input ends are respectively placed on the four focal points,...

Abstract

The invention relates to a microwave power confocal synthesis device. Aiming at the shortages that the microwave power synthesizer in the prior art has relatively high requirements on microwave sources, the system structure is complicated and the cost is high, the invention discloses a microwave power confocal synthesis device. The microwave power confocal synthesis device synthesizes the power of multiple paths of microwaves to obtain a large-power microwave, so that the cost of large-power microwave equipment is reduced. The technical scheme of the invention is that: the microwave power confocal synthesis device comprises at least two microwave input ends and the corresponding waveguide cavities. The waveguide cavity comprises a bottom surface, a top surface and a side wall vertical to the bottom surface and the top surface, wherein the bottom surface and the top surface are parallel to each other; the orthographic projection of the side wall on the bottom surface or the top surfaceis an elliptical arc; the microwave input end is arranged on a focus of the elliptical arc; the other focus of the elliptical arc is superposed and is a microwave gathering end; and the microwaves inputted by the microwave input ends are gathered at the microwave gathering end after passing through the waveguide cavities. The microwave power confocal synthesis device can be used for generating plasmas.

Description

technical field [0001] The invention relates to the intersecting field of microwave technology and plasma technology, in particular to a microwave power confocal synthesis device that can be used to excite plasma fireballs. Background technique [0002] Plasma fireball is a common natural phenomenon, often manifested as spherical lightning, terrestrial fireball and so on. In order to find out the cause of this phenomenon and its natural characteristics and laws, people have launched related research work since a long time ago. The record and study of the atmospheric fireball phenomenon are recorded in ancient books of our country, such as "Shan Hai Jing", "Historical Records" and other historical books. In other words, judging from ancient Chinese historical records, the research history of atmospheric fireballs is at least 2,000 years old. Even counting from F.Arago's first paper published in 1838, it has been more than 170 years. By the mid-1980s, there were about 2,000...
