Purpose – The paper aims to present an overview of techniques for the identification in the frequency domain of reduced order models for distributed passive electromagnetic structures. Design/methodology/approach – Most known approaches proposed in different application contexts are described within a unified framework. Findings – A passive reduced order model of an unshielded twisted pair is fully developed with the combination of vector fitting algorithm and the passivity enforcement via Hamiltonian perturbation. Originality/value – A state-of-the-art picture of the frequency domain identification and passivity enforcement techniques is given, and a test case of actual interest fully analysed. Keywords Electromagnetic fields, Frequency response, Identification, Modelling

Abstract

Purpose – The paper aims to present an overview of techniques for the identification in the frequency domain of reduced order models for distributed passive electromagnetic structures. Design/methodology/approach – Most known approaches proposed in different application contexts are described within a unified framework. Findings – A passive reduced order model of an unshielded twisted pair is fully developed with the combination of vector fitting algorithm and the passivity enforcement via Hamiltonian perturbation. Originality/value – A state-of-the-art picture of the frequency domain identification and passivity enforcement techniques is given, and a test case of actual interest fully analysed.
