论文摘要
光束驱动的辐射源的现代趋势涉及将Cherenkov Wakefield与具有复杂介电衬里的开放式圆形波导结构相互作用，最近提供了三层介电毛细管，以降低辐射差异为代表性的示例\ cite \ cite {Jiang2020}。本文介绍了严格的方法，允许对所述结构通过单波导模式激发电磁过程的分析描述。换句话说，在严格的公式中考虑了相应的规范波导衍射问题。这是我们最近的论文\ cite {gv2022}的延续，其中考虑了两层介电填充的更简单情况。在这里，我们使用基于Wiener-Hopf-Fock技术的相同分析方法，并处理更复杂的三层介电内衬的情况。
Modern trends in beam-driven radiation sources involve interaction of Cherenkov wakefields with open-ended circular waveguide structures having complicated dielectric lining, with a three-layer dielectric capillary recently offered for reducing the radiation divergency being a representative example \cite{Jiang2020}. This paper presents rigorous approach allowing analytical description of electromagnetic processes occuring when the described structure is excited by single waveguide mode. In other words, corresponding canonical waveguide diffraction problem is considered in rigorous formulation. This is continuation of our recent paper \cite{GV2022} where a simpler case of a two-layer dielectric filling has been considered. Here we use the same analytical approach based on Wiener-Hopf-Fock technique and deal with more complicated case of a three-layer dielectric lining.
