本文提出了两种射频窗口的计算机辅助设计（CAD），即双盘射频窗口和药盒型射频窗口，用于高功率微波/毫米波源。针对42GHz频段（TE0,3模式）和170GHz频段（高斯模式）进行了双盘式射频窗口设计，针对2.856GHz频段进行了药盒式射频窗口设计。 RF窗口设计的要求是最大限度地减少反射，并在所需的谐振频率下精确匹配。在本方法中，利用最近开发的粒子群优化（PSO）方法调用散射矩阵代码，以优化窗口的几何参数。使用 PSO 的多目标优化已用于实现所需谐振频率的匹配与最小化所需工作频带中的功率反射之间的优化权衡。
In this paper, computer-aided design (CAD) of two types of RF windows, namely, double-disk RF window and pillbox-type RF window, is presented for use in high-power microwave/millimeter-wave sources. The design of double-disk RF window was carried out for 42-GHz band (TE0,3 mode) and 170-GHz band (Gaussian mode), while the design of pillbox-type RF window was carried out for 2.856-GHz band. The requirement for the design of RF window is to minimize the reflections with exact matching at desired resonant frequency. In the present approach, a scattering-matrix code was invoked with recently developed particle swarm optimization (PSO) method in order to optimize the geometrical parameters of the window. Multiobjective optimizations using PSO have been used to achieve optimized tradeoff between matching of desired resonant frequency and minimizing the power reflections in the desired band of operation.
