Эти устройства благодаря своей способности эффективно генерировать, усиливать и фильтровать СВЧ-сигналы находят применение во многих научных направлениях. Исследованы резонаторы сложной формы, которые позволяют получить улучшенные электродинамичес­ кие характеристики взаимодействия с электронным потоком. Приведен расчет мод Hmnp и Emnp в резонаторе с азимутально-продольно нерегулярным сечением. Полученные решения основаны на проекционных методах при верификации с электродинамическим решением в аттестованном международном пакете CST Studio Suite.</p></abstract><trans-abstract xml:lang="en"><p>Modern use of vacuum microwave resonators covers many areas of science, technology and industry. These devices, due to their ability to effectively generate, amplify and filter microwave signals, are used in many scientific fields. Resonators of complex shape, which allow obtaining improved electrodynamic characteristics of interaction with an electron flow, are investigated. The calculation of the Hmnp and Emnp modes in a resonator with an azimuthally-longitudinally irregular cross-section is presented. The obtained solutions are based on projection methods during verification with an electrodynamic solution in the certified international CST Studio Suite package.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>резонаторы на модах Hmnp и Emnp</kwd><kwd>азимутально-продольно нерегулярный профиль</kwd><kwd>СВЧ-резонаторы</kwd></kwd-group><kwd-group xml:lang="en"><kwd>cavity at Hmnp and Emnp mode frequencies</kwd><kwd>azimuthal-longitudinally irregular section</kwd><kwd>microwave cavities</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Кураев, А.
