宽带集中元件环行器计算机辅助设计

CAD of Broadband Lumped-element Circulators

本文从散射矩阵本征值的频率关系出发,对宽带集中元件环行器所需的设计参数作了优化计算。文中采用乘子法将约束优化问题化为无约束优化问题。计算结果与实验结果较一致并证实了为得到宽带性能实验中出现的隔离双峰的现象。

The Parameters of a broadband lumped-element circulator are optimized by using the scattering matrix eigenvalue relative to the frequency. The method of multiplies is used to transform constrained optimization into unconstrained optimization. The results calculated are nearly in accordance with the experimental results and prove isolating double peaks in broadband circulator experiment.
