平面结环行器的优化设计

Optimum Design of Planar Junction Circulator

本文首先证明了用边界元分析结平面环行器的过程及程序的有效性和通用性。接着,优化处理了平面结环行器的有关参数,优化分两步,第一步是在结形状不变的情况下,用步长加速法优化圆结半径,耦合角及结外介质的介电常数;第二步是在第一步的基础上,用Powell方法优化结形状。最后给出了优化实例。

In this paper, the analysis of a planar junction circulator with an arbitary junction shape by boundary element method is reported. And it is showen hat the optimum ju ction shape fora planar circulator with given bandwidth can be ound by powell's method.
