摘要
提出了一种适用于毫米波行波放大器的慢波电路——沟道板慢波电路,该慢波电路的基本结构与沟道梯型慢波电路相似,但其环与金属壁间使用金属板相连。使用场论方法分析了沟道板慢波电路,得到的色散结果与CST的模拟结果之间的误差在1.5%以内。计算表明,沟道板慢波电路与沟道梯型慢波电路的耦合阻抗特性相似,且沟道板电路的色散相对较弱,具有更宽的带宽。
A new kind of slow-wave circuit, tunnelplane, is put forward. The tunnelplane circuit was similar to tunneladder slow-wave circuit, but the support between the ring and the metal wall is a metal plane. The tunnelplane was analyzed by field method. The discrepancy of dispersion between the analysis and CST was within 1.5%. The analysis shows that the tunnelplane structure has relatively broader band than the tunneladder structure, and both of the structures have high interaction impedance.
