Fully automated space mapping optimization of 3D structures

Abstract

We present new results of fully automating the aggressive Space Mapping (SM) strategy for electromagnetic optimization. The generic SM update loop and the model-specific parameter extraction loop are automated using a two-level Datapipe architecture. We apply the automated SM strategy to the optimization of waveguide transformers. We introduce a multi-point parameter extraction procedure for sharpening the solution uniqueness and improving the SM convergence. We present, for the first time, automated electromagnetic optimization utilizing the commercial 3D structure simulator HFSS.
