Separation field reconstruction test platform

Abstract

The invention relates to a separation field reconstruction test platform. The separation field reconstruction test platform comprises a vector network analyzer, a coaxial line, a waveguide coaxial converter, a coupling window, a separation field reconstruction main body, a separation field reconstruction cavity, a mounting groove, a quartz tube and a sample. The coaxial line is arranged at one side of the vector network analyzer, and the waveguide coaxial converter is arranged at one side of the coaxial line, which is away from the vector network analyzer, wherein the quartz tube is arranged at one side of the mounting groove, which is away from the separation field reconstruction main body; and the sample is arranged inside the quartz tube. According to the separation field reconstructiontest platform, the separation field reconstruction cavity is formed by two orthogonal single mode cavity systems; two single mode cavities work in different modes and respectively form an electric field center and a magnetic field center at the position of a tested material; and by measuring an S parameter at the input ends of the two single mode cavities through algorithms such as a neural network and the like, a dielectric constant and magnetic conductivity of the material can be inverted so as to guarantee the magnetic conductivity not to influence a measurement result; the separation field reconstruction test platform is simple to operate; time is saved; and engineering efficiency is improved.

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 ...
