Adaptive Design Specifications and Coarsely-Discretized EM Models for Rapid Optimization of Microwave Structures with FEKO
S. Koziel
Reykjavik University, Iceland
An efficient procedure for design optimization of microwave devices simulated in FEKO is discussed. Our approach exploits recently introduced adaptively adjusted design specifications technique that shifts the optimization burden into a relaxed-accuracy and computationally cheap (low-fidelity or coarse) model of the structure under consideration, also evaluated in FEKO but with coarse discretization. The unavoidable misalignment between the coarse and the original (high-fidelity or fine) model is accounted for by suitable adjustments of the design specifications. The presented method is simple to implement and allows rapid design improvement as demonstrated through examples.
