A new space mapping optimization algorithm for microwave design is presented. We implement a distributed fine model evaluation through independent processing of the fine model responses corresponding to consecutive frequency samples using a number of processors. This allows us to obtain a substantial reduction of the overall optimization time for the space mapping algorithm. When our technique is used together with previously published methods of reducing the computational cost of solving the parameter extraction and surrogate optimization sub-problems, the total optimization time of the microwave structure can be comparable to or less than a single fine model evaluation on a single processor. Illustration examples are provided.
