基于隐式空间映射算法微波滤波器的优化设计

Microwave Filter Optimal Design with Implicit Space Mapping Algorithm

该文叙述了隐式空间映射算法的方法,并应用隐式空间映射法优化设计了中心频率为5.5GHz,通带带宽为800MHz的超宽带微波平行耦合谐振滤波器。滤波器经过3次的迭代达到了设计指标,减少了在精确模型中的仿真次数,与通常电磁仿真软件的参数扫描相比优化效果明显。

This paper describes an approach of implicit space mapping（ISM） which is further used to design and optimum a parallel resonant coupling filter. The filter owns center frequency of 5.5 GHz and the band- width of 800MHz. After three iterations, the filter reaches the specifications. Therefore, this method decreases the times of simulation in the fine models. In comparison to the parameters sweep in the electromagnetic simu- lation, the optimization is obvious.
