Identification of broadband passive macromodels for electromagnetic structures

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.
