Passivity Enforcement of Loewner Matrix Macromodels Using Singular Value Perturbation

In this paper, passivity enforcement based on singular value perturbation is applied to non-passive macromodels generated using Loewner Matrix Interpolation. The method is compared with recent methods based on Hamiltonian Matrix eigenvalue perturbation. The singular value perturbation method is shown to be an accurate and cpu cost efficient alternative to the Hamiltonian method.
