Abstract :
A systematic general-purpose technique for the extraction of equivalent circuits of lumped discontinuities and interconnects from full-wave electromagnetic-field numerical data is presented. The main feature of the method consists of approximating the simulated data in order to generate a passive and feasible circuit in an automatic way. All the aspects of the methodology are addressed. Particular emphasis is laid on the approximation step, about which a new technique is proposed
