中文摘要：
以Cumow等效电路为依据，基于基尔霍夫电压和电流定理，获得了通用Curnow等效电路模型的色散、总阻抗的计算方法；从设计角度出发，根据色散和总阻抗计算方法，以实际结构为例，探讨了在保证整个工作带宽内，器件的工作频率和相速基本不变的情况下，腔体结构参数变化对总阻抗的影响，并以此为依据，对原有结构参数进行了优化，从而提出了一种可用于耦合腔行波管高频结构优化的方法。
英文摘要：
The high frequency structure of the coupled-cavity traveling wave tubes was modeled, calculated, opti- mized and redesigned. In the optimization, the formula, involving the dispersion and total impedance, were firstly derived with Kirchhoff＇s laws of current and voltage on the basis of Curuow equivalent-circuit model; next, the impacts of the dif- ferent structures on the total impedance of the TWT was evaluated, based on the formula of the dispersion and the total impedance,trader the conditions of a fixed working frequency and a phase speed in the full band range; and finally,the conventional structure was optimized and redesigned. The possible application of the newly-developed optimization tech- nique to the design of other coupled-cavity TWTs was also tentatively discussed.
