摘要
基于矢量分解思想和波导内场分布特性,分析了极化特性和孔缝位置对腔体谐振特性的影响规律。首先将平面波在直角坐标系中分解,根据平面波分量在波导内产生的不同场分布形式,引入极化模式因子和位置模式因子对出现的腔体谐振模式进行分析。CST(computer simulation technology)仿真结果说明,极化模式因子和孔缝位置因子能准确描述腔体谐振模式的产生规律。研究结论可为腔体结构设计中快速、准确判断腔体谐振模式提供参考。
The influence of polarization property and aperture position on the cavity resonant modes is analyzed based on vector de-composition and filed distribution inside the waveguide. Firstly, the plane wave is decomposed in the Cartesian coordinates. Then, based on different field distributions generated by the plane wave components within the waveguide, polarization and posi-tion mode factors are introduced to analyze the cavity resonant modes. Simulation results via CST （computer simulation technolo-gy） software show that the polarization mode factor and the position mode factor can describe the occurring cavity resonant modes accurately. The research results help to estimate the cavity resonant modes quickly and accurately in engineering practice.
