Common-pole modeling of frequency responses can be time consuming for systems with highly resonant responses. This letter presents a Barycentric Vector Fitting algorithm that improves the running time of existing Vector Fitting algorithms. The effectiveness of the approach is demonstrated by applying it to coupled microstrip lines. Numerical results confirm the accuracy of the model and the savings in computation time.
