A space mapping method allowing models with different parameter rank and physical meanings for coarse and fine model

Automated optimization of complex microwave circuits is still a critical task in nowadays. This contribution demonstrates two new approaches in space mapping technology. One substantial benefit is the improvement of calculation efficiency of the TRASM algorithm by enhancing the multiparameter extraction step. Furthermore, the possibility of mapping coarse and fine models of different degrees of freedom, i.e. with different parameter rank, and unequal physical parameter meanings has been introduced to the method. Therefore, arbitrary microwave circuits of high complexness with well-matching coarse models can be efficiently and automatically optimized.
