摘要

药盒介电窗是真空电子器件的关键部件。使用回溯搜索算法（BSA）进行优化设计有助于确定精确的设计变量，以实现2.998 GHz的期望频率和最大带宽。最优设计变量为腔长$C_{l}$为27 mm，腔半径$C_{r}$为33.3 mm。将pareto多目标回溯搜索算法（PMBSA）与和谐搜索算法（HSA）、多目标粒子群优化算法（MOPSO）和非支配排序遗传算法（NSGA-II）进行对比，验证其性能。使用C-metric和间距（SP） metric分析评估这些算法的质量，结果以箱形图表示。两种分析都表明PMBSA具有良好的效果。

Optimization and Algorithm Quality Measure in the Design of Pill-Box Dielectric Window

The pill-box dielectric window is a key component in vacuum electron devices. Using the backtracking search algorithm (BSA) for its optimal design helps identify the precise design variables needed to achieve a desired frequency of 2.998 GHz and maximize bandwidth. The optimal design variables are a cavity length (

$C_{l}$

) of 27 mm and a cavity radius (

$C_{r}$

) of 33.3 mm. The pareto multi-objective backtracking search algorithm (PMBSA) algorithm’s performance was validated against well-known algorithms harmony search algorithm (HSA), multi-objective particle swarm optimization (MOPSO), and nondominated sorting genetic algorithm (NSGA-II). The quality of these algorithms was assessed using C-metric and spacing (SP) metric analyses, with the results presented in a box plot. Both the analyses suggest that PMBSA offers favorable results.
