M.vde Magistris, L. De Tommasi

• 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.
