Abstract :
This paper introduces a new scheme for the identification of multivariate behavioral macromodels from tabulated frequency-domain data. The method produces closed-form parametric expressions that reproduce with excellent accuracy the external port behavior of the structure, both as function of frequency and one or more external parameters. The numerical robustness of the main algorithm is demonstrated on two significant examples.
