Tuning Space Mapping: A Novel Technique for Engineering Design Optimization

We introduce a tuning space mapping (TSM) technology for microwave design optimization. For the first time, we formulate the novel TSM concept and show how it relates to the standard space mapping methodology. The new method is based on a so-called tuning model that is created using engineering expertise and knowledge of the design problem, but also utilizes the efficiency of space mapping for translating the adjustment of the tuning parameters into relevant updates of the design variables. We illustrate our approach through optimization of a high-temperature superconducting (HTS) filter.
