Automatic optimal design for robust multi-cavity filter

将膜系容差纳入评价函数 ,提出了多腔窄带滤光片鲁棒性设计的概念和方法 .阐述了理论分析的依据 ,在修改的程序基础上得出一组优化设计的膜系 .结果表明这种方法得到的膜系不一定是最优的理论解 ,但一定是最优的实际解 .膜厚灵敏度因子计算结果表明 ,鲁棒性膜系较其他膜系的敏感度因子要低 。

A new concept of design for multi cavity narrow band filter is provided in this paper. By adding film system tolerance to evaluation function, a theoretical analysis is presented. Based on the modified film system deposition programme, a group of optimal result is reached. It shows that the film system is not a theoretical optimum result but a practical optimum result. The sensitivity gene is calculated and the result shows that the robust film system has much lower sensitivity gene compared with other film system, demonstrating the correctivity of optimal result.
