论文摘要
摘要 - 我们基于拉格朗日田地理论构建了一个分析模型，用于在波动波管（TWT）中分散热模式，将其常数升级为频率依赖性。 TWT慢波结构（SWS）参数的频率依赖性通过标准软件（例如CST）从全波模拟中恢复。我们应用了该模型来研究基于螺旋的TWT的热模式，并发现了模型的结果与细胞（PIC）模拟中粒子的结果之间的一致性。我们的其他研究表明，所提出的方法可以应用于各种SWS几何形状。
Abstract -- We construct an analytical model for the dispersion of the hot modes in a traveling wave tube (TWT) based on the Lagrangian field theory, upgrading its constants to be frequency-dependent. The frequency dependence of the parameters of the TWT slow wave structure (SWS) is recovered from full-wave simulations by standard software (e.g., CST). We applied the model to study the hot modes of a helical-based TWT and found an excellent agreement between the results from our model and those from particle in cell (PIC) simulations. Our additional studies show that the proposed approach can be applied to various SWS geometries.
