| 摘 要： | 用矩量法(MOM)导出求解X波段波导端头裂缝口面等效磁流的公式。在此基础上,计算波导不同频率下的反射系数和驻波系数等参数。给出了BJ-100波导端头裂缝口参数的计算结果,据此讨论了裂缝长度、宽度、厚度与谐振频率的关系。另外检验了圆头与方头裂缝的等效性,并给出了波导端头裂缝谐振频率的近似设计公式。分析结果表明,该算法简单,计算结果与测试值吻合较好。

| Abstract: | The equation to calculate the equivalent magnetic current of X band slot in the end wall of waveguide by moment of method(MOM) was derived in this paper.And the parameters such as reflection coefficient and standing wave coefficient were computed based on the method.The numerical computation results of the parameters for BJ-100 waveguide slot were given.The relationships between the length,width and thickness of the slot and resonant frequency were discussed based on the calculation.The equivalent of the rectangular slot and circular slot was proved,and the approximate formula about the resonant frequency was presented.The analysis results showed that this method was simple,which computation result was similar with the measurement. |
