摘要 应用边界元法对矩形波导插入圆腔结构的不连续性问题进行了分析,编制了一个计算机程序,对这种结构的散射系数进行了计算,其结果与文献(东南大学学报(自然科学版),2000,30(1):42~46)值一致.通过分析和计算表明,这是一种有效的数据计算方法. In this paper, the boundaryelement method is used for the analysis of the discontinuities of waveguidecylindrical cavity. A computer program is developed and the scattering coefficients of this system are calculated. The results well agree with the data in reference(J. Southeast University (Nat. Sci.),2000,30(1):42~46).
