| 摘 要： | 设计基于圆形槽波导的元件经常会用到圆形槽波导到矩形波导结.应用有限元法(FEM)分析了N端口波导结.采用完全匹配层(PML)将槽波导的开放边界截断为有限区域,然后对圆形槽波导到矩形波导结的散射特性进行了数值计算,得出的散射参量为圆形槽波导振荡器输出结构的优化设计提供了依据.

| Abstract: | Circular groove to rectangular waveguide junction is a frequent component for devices design based on circular groove guide. In this paper, N-port waveguide junction was analyzed by the finite element method (FEM). To fulfill the requirement of limited domain which FEM can process, perfectly matched layer (PML) was applied to truncate the open boundary of groove guide. Then, scattering parameters of circular groove to rectangular waveguide junction were calculated. The numerical results can be used to design and adjust circular groove guide oscillators. |
