摘要

本文针对微波波导滤波器提出了一种融合单步渐进空间映射（One-Step Aggressive Space Mapping，OS-ASM）和隐式空间映射（Implicit Space Mapping，ISM）的高效复合优化策略.单步渐进空间映射能使远离最优解的初值迅速向最优解附近靠近，再辅以隐式空间映射优化，一般五步迭代以内即可使基于物理结构的微波波导滤波器高精度模型（精细模型（Fine Model， FM））仿真结果与目标理论特性几近完美拟合.与传统直接优化算法相比，本策略并非对精细模型直接进行迭代优化，而是对基于模匹配法的低精度模型（粗糙模型（Coarse Model，CM））迭代计算，精细模型仿真仅用于验证迭代优化粗糙模型生成的物理参数，时效性极高，同时也回避了单步渐进空间映射中粗糙模型必须实现极致拟合的严苛要求.本文以八阶切比雪夫型矩形波导滤波器（Bandpass Filter，BPF）和四阶双模圆波导滤波器为例，详细阐释了该策略的实施过程及效果.

Abstract

This paper presents an effective mixed space mapping (MSM) strategy for microwave waveguide filters by incorporating the one-step aggressive space mapping (OS-ASM) and the implicit space mapping (ISM). Executing OS-ASM enables the initial physical parameters to rapidly reach the proximity of the best solution

even if the initial parameters locate far away from the targetted ones. The further conducted standard ISM steps empower the simulation results of the high-fidelity model or the fine model (FM) of the waveguide filters almost perfectly to match the specified theoretical porformance within few iteration steps. Compared with the traditional direct optimization methods

the proposed MSM strategy does directly and iteratively optimize the low-fidelity model or the coarse model (CM) based on the mode-matching technique with small computation burden

and the few performed FM simulations with large computation consumpation are only used to verify the physical parameters produced by optimizing the continuously calibrated CM

and that is why substantial efficiency and accuracy are simultaneoulsy achieved

and in addition

the demanding requirement that the CM must be able to realize the extreme fitting in the traditional OS-ASM is greatly relieved. An eight-pole Chebyshev rectangular waveguide bandpass filter (BPF) and a four-pole dual-mode circular waveguide BPF are taken as examples to detail the implementation process and the eminent effects of the proposed MSM strategy.
