摘要: 运用有限积分法软件MAFIA和有限元软件ANSYS对两类高频腔的本征值问题进行数值模拟，将模拟结果与部分实验数据进行验证，得到了比较一致的结果，其平均计算精度在5%以内，证实了两种电磁软件都可用于高频腔本征值问题的数值模拟，在计算精度上为满足工程设计需要做了一些研究。另外将两种模拟软件在计算时间上作了对比。Abstract: This paper presents the numerical simulation method by Finite Integration Method softwareMAFIA and Finite Element Method softwareANSYS to calculate Eigenvalue and Q value in two kinds of high frequency cavity. The simulation result are good consistency with part experiment data; The average calculation precise may be less than 5%. It proves that both electromagnetic software are capable of simulating eigenvalue problems in high frequency cavity, making some research for compute simulation to satisfy practical engineering design demand in computation precise. The calculation time is compared for the both software.
