Multi-delay rational modeling of lumped-distributed systems

Adaptive Frequency Sampling Based on Local Rational Modeling for Microwave Electromagnetic Simulations

“…To reach 750 samples with the VF-based algorithm, it took more than one day of estimation time. While the accuracy of the standard VF model can be improved by employing multi-delay rational modeling techniques [33], [34], this topic is beyond the scope of the current paper. However, irrespective of a global model, we can evaluate the model prediction quality of the local rational models across the entire frequency range.…”
