On space mapping optimization with coarsely-discretized EM coarse models

摘要

Here, a study of SM algorithms with coarsely-discretized EM coarse models is presented. In particular, new and efficient parameter extraction and surrogate optimization schemes are proposed that make the use of coarsely-discretized EM models feasible for SM algorithms. Robustness of our approach is demonstrated through the design of two microstrip filters and a double annular ring antenna.
