An Efficient Yield-Constrained Design Framework Using Global Surrogates for Microwave Filters

In this work, an efficient framework is designed to obtain the optimal design solutions with a high yield. In the proposed framework, all objectives are modeled using the Polynomial chaos method. The optimal design with the yield-constrained is obtained using a global optimizer. A four-pole waveguide microwave filter example is used to verify the performance of the proposed method. The proposed framework does not require an initial design. The electromagnetics simulated verification results show that the proposed framework obtains a better design with a higher yield using lower computational cost than a Monte Carlo-based method and a state-of-the-art yield optimization method.’
