摘　　要：介绍了复杂边界条件的圆形槽波导的有限元分析方法和边界处理方法。利用完全匹配层(PML)对圆形槽波导的开放边界进行截断,应用有限元法计算W波段圆形槽波导中径向盘位置和厚度对径向盘输入阻抗的影响,数值结果的分析可供设计圆形槽波导中径向盘时参考。The structure characters and application development of circular groove-guide are described simply. The finite element analysis method and boundary disposal method are introduced about the complex boundary in the circular groove-guide. Perfectly matched layer (PML) is applied on the open boundary of circular groove guide. The influence of the disposition and thickness of radial disk on the input impedance in circular groove-guide is calculated by the finite element method (FEM) in W-band. The numerical analysis results are very useful to design the radial disk in circular groove-guide.
