摘要: 苜蓿叶形耦合腔慢波结构是一种高耦合阻抗的慢波线。由于结构复杂，其数学分析及工程设计都非常困难。该文利用三维电磁计算软件Isfel3d，Mafia，HFSS对这种结构的色散特性、耦合阻抗进行数值模拟，在分析模拟结果的基础上，对这种结构做了初步的优化。结果表明，数值模拟与实验结果有很好的一致性，这对改进这种慢波线的工程设计具有重要意义。Abstract: Clover-leaf coupled cavity is a kind of slow-wave structure of high interaction impedance.The mathematic analyse and the engineering design are very difficult for its complex structure.In this paper, three- dimensional simulation codes Isfel3d，Mafia，HFSS are used to determine the dispersion and interaction impedance.Based on analyse of simulate results,the coupled cavity slow-wave structure is optimized primarily.The simulation results is consistent with the measurement results and is significant to design of the slow-wave structure.
