| 摘 要： | 用矩量法(MOM)导出求解矩形开口波导口面等效磁流的公式,并在此基础上计算波导不同频率处的驻波系数、辐射方向图等参数。给出了BJ-100,BJ-58两种开口波导的计算结果,并据此讨论了等效磁流中不同模次所占的比例。计算结果表明,MOM计算结果与测试数据吻合良好。对单波导,口面分为5个窄条、每窄条基函数展开至5次即可较准确地算得驻波系数和辐射方向图等参数。

| Abstract: | The equation to calculate the equivalent magnetic current of open-end rectangular waveguide by moment of method(MOM) was derived in this paper.And the parameters such as standing wave coefficient,pattern and etc.were computed based on the equivalent magnetic current.The computation results for BJ-100 and BJ-58 waveguide were given.The different ratios for various numbers of lath in the equivalent magnetic current were discussed.The results showed that the computation by MOM was agreed with test data very well.The parameters of standing wave coefficient,pattern and etc.would be gained correctly when the waveguide face was divided into 5 lathes and the base function was deployed to 5 order for single waveguide. |
