Optimization of Non-Linear Feeds to Broadband Radiating Systems Using Transient Port-Extraction

The ability to optimize transient systems comprising broadband electromagnetic (EM) devices fed by strongly non-linear circuits is of great interest in a number of design applications. However, existing techniques to optimize these systems are computationally infeasible for large-scale problems due primarily to the cost associated with solving the EM system. In this work, we propose a model order reduction technique based around transient port extraction to efficiently optimize a non-linear EM-circuit system. We show through numerical results that our method agrees with a traditional self-consistent solve, while being less computationally expensive.
