Abstract
The utility model relates to the technical field of microwaves and discloses a material microwave absorption analyzer. The material microwave absorption analyzer comprises a sample room which is connected with a waveguide chamber, wherein a circulator is arranged in the waveguide chamber in the coaxial transition direction and is connected with a vector network analyzer which is provided with a screen, and a signal input port and a signal output port are arranged below the screen. By virtue of the total reflection principle of the waveguide chamber, materials entering into a system are totally reflected and total reflection signals are detected at a detection port. When a material is placed in the sample room and absorbs certain microwave energy, an absorption peak of a certain frequency of the material is observed on the screen of the vector network analyzer, and the absorption frequency of the material is found so as to further research and analyze various effects of microwaves at the frequency to the material. The material microwave absorption analyzer provided by the utility model is simple to operate and convenient to read and provides a means for analyzing microwave absorption of materials.
Description
Technical field
The utility model relates to microwave technical field, has related in particular to a kind of material microwave absorption analyser.
Background technology
The character of microwave is the same with light wave, and general object can produce three kinds of phenomenons in microwave field: reflection, transmission and absorption, now also do not have a kind of instrument in order to analyze the absorption of material to microwave.
Summary of the invention
The utility model, for shortcoming of the prior art, provides a kind of material microwave absorption analyser.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals:
Material microwave absorption analyser, comprises sample chamber, and sample chamber connects waveguide cavity, the coaxial conversion direction circulator of waveguide cavity, circulator connected vector network analyzer, vector network analyzer is provided with screen, and screen below is provided with signal input port and signal output port.Different tested materials can be put in sample chamber.Microwave absorption analyser is a full reflected system, put into after analyzed material, if material does not absorb microwave, the microwave energy that enters system is almost all reflected, if material absorbs the microwave of a certain wavelength, the signal of detection of reflected just can be seen the absorption peak of this material to a certain frequency range microwave on network analyzer, find out after the absorption frequency of this material, thus the further various effects of this frequency microwave of deep study and analysis to material.Here, the particle of different wave length that material refers to.
As preferably, circulator is provided with three ports, three ports are respectively circulator the first port, circulator the second port and circulator the 3rd port, circulator the second port is connected with waveguide cavity, circulator the first port is connected with signal output port, and circulator the 3rd port is connected with signal input port.
The utility model, owing to having adopted above technical scheme, provides a kind of instrument of analyzing material absorption microwave:
The utility model utilization system stream is analyzed the material of putting into system the total reflection principle of microwave, on vector network analyzer, observe the absorption peak of material to a certain frequency range microwave, find out the absorption frequency of this material, and then the various effects of this frequency microwave of deep study and analysis to material, the utility model is simple to operate, read conveniently, accurate rate is high.
Brief description of the drawings
Fig. 1 is system construction drawing of the present utility model.
The toponym that in accompanying drawing, each number designation refers to is as follows: 1-sample chamber, 2-waveguide cavity, 3-circulator, 4-vector network analyzer, 5-screen, 6-signal input port, 7-signal output port, 8-circulator the first port, 9-circulator the second port, 10-circulator the 3rd port.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail.
Embodiment 1
Material microwave absorption analyser, as shown in Figure 1, comprise sample chamber 1, sample chamber 1 connects waveguide cavity 2, the coaxial conversion direction circulator 3 of waveguide cavity 2, circulator 3 connected vector network analyzers 4, vector network analyzer 4 is provided with screen 5, and screen 5 belows are provided with signal input port 6 and signal output port 7.
Circulator 3 is provided with three ports, three ports are respectively circulator the first port 8, circulator the second port 9 and circulator the 3rd port one 0, circulator the second port 9 is connected with waveguide cavity 2, circulator the first port 8 is connected with signal output port 7, and circulator the 3rd port one 0 is connected with signal input port 6.
Principle of work and operation:
After whole device connects, the reflected signal of system is detected by circulator the 3rd port one 0 of circulator 3,
When not having material to enter waveguide cavity 2 in sample chamber 1, the microwave signal of sample chamber 1 will all reflect, and be detected by circulator the 3rd port one 0, now, show a constant amplitude straight line on screen 5;
In the time putting into material in sample chamber 1, if material does not absorb the microwave signal of this frequency range, material enters waveguide cavity 2, and the microwave signal total reflection of sample chamber 1 shows a constant amplitude straight line on screen 5;
When putting into material in sample chamber 1, this material has absorption to a certain frequency of this frequency range microwave, and the microwave energy being absorbed by material can not be reflected, and shows like this curve with absorption peak on the screen 5 of vector network analyzer 4.
In a word, the foregoing is only preferred embodiment of the present utility model, all equalizations of doing according to the utility model claim change and modify, and all should belong to the covering scope of the utility model patent.
