Abstract

Microwave resonant cavity of internal electromagnetic field distribution in space three coordinate direction will be limited, all into standing wave distribution. Microwave resonator in microwave circuits plays and low frequency oscillation loop of the same role LC, is one kind has the energy storage and choose the resonance frequency characteristics of the device. The main research rectangular resonant cavity and cylinder of resonance cavity characteristic parameters of the calculation and simulation calculation with vc + +. When the MFC write a small interface calculation tool, when the input variable parameter, similar calculator form output calculation result directly, and the simulation software for HFSS, used for rectangular resonant cavity and cylindrical a rectangular resonant cavity simulation, the input variables that the simulation results and the results were compared with the settlement. This paper first introduces the development of microwave resonator and prospects and theoretical knowledge and MFC, Hfss and software. And then, the:

1. To metal in a resonant cavity characteristic parameters of the characteristics and calculation way further discusses the basic characteristics and learning basic analysis method.

2. Rectangular resonant cavity and cylindrical resonator parameters calculation in small interface calculated method, and an example is said that the calculation results input variables.

3. With Hfss microwave technology simulation software of the rectangular resonant cavity and cylindrical resonant cavity, and the results of the simulation before the comparison.

4. In a small interface computing tools in different size, internal filling input, and different material with copper, iron, aluminum and other materials as a resonant cavity surface material, etc cases calculated, different results, and the simulation software of the rectangular cylinder and resonant cavity simulation, two sets of data and compared to obtain the result.

This paper makes a study of the metal in a resonant cavity rectangular resonant cavity and cylindrical resonator characteristic parameters of the characteristics and calculation method, and the characteristic parameters of the method for calculating the characteristics, further research and study, and then use of its programming software programming, get a convenient calculation tool, and in rectangular cylinder and resonant cavity simulation, the results and simulation results is discrimination computing tools of practicality and convenience.
