The network-oriented ultra wideband transfer function representation of complex three-dimensional electromagnetic structures is investigated. The transfer function consists of two parts: entire function and rational or pole function. System identification is carried out by the matrix pencil method (MPM) and a new criterion for the choice of the model order and the late-time border of the impulse response is presented. This criterion is based on a pole set comparison by using the E -pulse method. The presented method yields considerable reduction of computational effort and allows to generate compact models of electromagnetic systems.     «
