The waveguide is a structure for directionally guiding electromagnetic waves.
The three-pin tuner is based on the principle of a stub tuning method and realizes the matching of load admittance in a larger range. The microwave plasma impedance matching device can be applied to various industrial microwave heating devices and microwave plasma devices to carry out impedance matching on a microwave transmission system.

Therefore, the plasma catalytic reforming formed by combining the discharge plasma with the traditional catalytic reforming technology has wide market application prospect and important scientific research significance.
Under the condition of atmospheric pressure, a relatively stable non-equilibrium discharge plasma generally needs to apply a strong electric field to a narrow discharge air gap, and a processed object can only be placed in the discharge air gap, so that the structure and the size of the processed object are limited by the distance between the discharge air gaps, and the strong electric field generally needs to be formed under the excitation of an externally applied kV-level high-voltage power supply, so that the device of the atmospheric pressure discharge plasma is high in manufacturing cost.
The Atmospheric Pressure Plasma Jet (APPJ) breaks through the limitation of the traditional gas discharge, can realize the separation of a discharge area and a working area space, and can also generate the Atmospheric Pressure non-equilibrium discharge Plasma with low gas temperature and high chemical activity by a simple device structure. In addition, the APPJ can directly transport the charged particles and the active substances to the surface of the object to be treated and directly complete the treatment process, and has no special requirements on the external shape, the geometric dimension and the surface morphology of the object to be treated.

The microwave resonant cavity is formed inside the annular waveguide. The circular output port of the conversion waveguide enables the microwave energy to be equally transmitted in two paths in the annular waveguide. Under the combined action of the slit and the large slit in the annular waveguide and the restriction of the geometric dimension of the microwave resonant cavity, the microwave energy forms TE mainly under the action of the large slit in the microwave resonant cavity11And TM01Equal mode and slit dominated TE41And the like.
