HFSS(High Frequency Structure Simulator) was used to calculate the S parameter of the different structural microwave chemistry reactor made of rectangular waveguide resonator,while changing the structure dimension of the microwave chemistry reactor such as shape and dimensions of iris,diameter of reaction tube and thickness of reaction tube wall,material and positions of reaction tube.

Study of racetrack waveguide resonator filter fabricated by ion-exchange technique;

The analysis and design for the microwave cavity in laser-cooled Rb fountain clock developed by ourselves were presented and the basic parameters of the microwave cavity developed were designed in this paper.

According to the modulation of mi-crowave cavity on different input signals,this paper judges the relationship between the frequency of input signal and the reso-nant frequency of microwave cavity through amplitude discrimination and phase demodulation,then,we use MCU to control the output frequency of VCO to .

When using a microwave resonator for steam wetness measurements,deposited liquid droplets form a water film on the resonance cavity s inner surface.

The resonator plays a role of wetness sensor in the process of steam wetness measuring based on microwave resonator perturbation.

Start with the choice of resonance model,introduces the practical process of structure design of microwave resonator in details.

The error of atmospheric structure explore equipments in common is bigger,based on the change principle of the resonance frequency of microwave resonant cavity when the medium enters into it is different,digital tester about atmosphere duct is designed.
