A reconfiguration test platform for separation field

Abstract

The invention relates to a separation field reconstruction test platform, comprising a vector network analyzer, a coaxial line, a waveguide coaxial converter, a coupling window, a separation field reconstruction body, a separation field reconstruction cavity, an installation groove, a quartz tube and a sample , one side of the vector network analyzer is provided with a coaxial line, and the side of the coaxial line away from the vector network analyzer is provided with a waveguide coaxial converter, wherein the quartz tube is provided in the installation groove away from the separation field One side of the reconstituted body with the sample placed inside the quartz tube. The separation field reconstruction test platform, the separation field reconstruction cavity is composed of two orthogonal single-mode cavity systems, and the two single-mode cavities work in different modes, respectively forming the electric field center and the magnetic field center at the test material. The measurement of S parameters at the input end of two single-mode cavities can invert the dielectric constant and magnetic permeability of the material through neural network and other algorithms to ensure that the magnetic permeability will not affect the measurement results. It is easy to operate, saves time and increases engineering efficiency. .

Description

technical field [0001] The invention relates to the technical field of separation field reconfiguration, in particular to a separation field reconfiguration test platform. Background technique [0002] Microwave has been widely used in material processing, chemical reaction, etc., and material properties have a very important impact on the microwave processing process. In the process of system design and simulation, it is necessary to understand the dielectric constant and magnetic permeability of materials. and other parameters. [0003] However, the existing microwave material testing system can only measure the dielectric constant of the material, and cannot distinguish the dielectric constant and magnetic permeability of the material. [0004] In the traditional measurement method, if the material has a certain magnetic permeability, the magnetic permeability will be mismeasured as a part of the permittivity, resulting in inaccurate measurement results. Therefore, this ...
