摘要: 采用谐波互作用的行波管二维大信号非线性理论，建立了高频电路结构和外部工作条件零散模型，对影响增益、相位频率特性的主要因素进行了理论分析和数值计算，开发了可动态实时显示行波管工作状态的可视化科学计算软件，并利用该软件全面地分析了某管型的幅相一致特性，为新近研制的幅相一致行波管提供了很有价值的计算结果。Abstract: Designing an octave bandwidth helical traveling wave tube(TWT) for phase and gain matched operation in the EHF region presents many obstacles, for example the dimensional controls.Recent advance in computer modeling offer the possibility to evaluate the effect of slow-wave structure parameter and operating parameter variations, such as manufacturing tolerances, which will enable manufacturers to determine the cost effectiveness of controlling the dimensions of the component parts of the TWT. In this paper, computer code PGMTWT is programmed, which includes helical slow-wave circuit code and 2-Dimensional large-signal including harmonics interaction helical TWT interaction code. The effect on curve of gain and phase dispersion for frequency, when helical slow-wave circuit parameter and oper
