A novel implementation of a space-mapping (SM) algorithm for optimisation of microwave structures and devices is described. The algorithm uses two techniques to speed up the SM optimisation process: the evaluation of the fine model is distributed through independent processing of the fine model response corresponding to consecutive frequency samples using a number of CPUs, and the parameter extraction and surrogate optimisation sub-problems are solved using built-in optimisation capabilities of the coarse model simulator. As a result, the optimisation time of microwave structures can be reduced to values comparable to or smaller than the time necessary for a single fine model evaluation on a single processor. This new implementation can be applied whenever the fine model is evaluated using a frequency-domain simulator. The robustness of this algorithm using microwave design optimisation problems is verified. The efficiency is compared with the standard implementation of the SM algorithm. [ABSTRACT FROM AUTHOR] |
