本文提出了一种基于连续体设计灵敏度分析并结合标准电磁分析代码的介质波导滤波器优化设计新方法。为此，首先利用增广拉格朗日法、物质导数概念和伴随变量法，系统地推导了频域解析灵敏度公式；然后提出了将多个工程软件包集成为一个设计工具的统一程序体系结构，用于高频器件的优化设计。在波导滤波器中使用了一个三维介质谐振腔，实验证明了该方法的有效性。
This paper presents a new methodology for design optimization of dielectric waveguide filters based on the continuum design sensitivity analysis in conjunction with standard electromagnetic analysis codes. To achieve this, first, an analytical sensitivity formula in the frequency domain is systematically derived by exploiting the augmented Lagrangian method, material derivative concept and adjoint variable method. Then unified program architecture integrating several engineering software packages into a design tool is proposed for optimum design of high-frequency devices. A 3-D dielectric resonator used in waveguide filters has been tested to prove the validity of the proposed method.
