Abstract

Krylov subspace-based model order reduction (MOR) of finite element models of electromagnetic structures Is not readily applicable when the electromagnetic properties of the materials exhibit arbitrary frequency dependence. This paper presents a methodology for overcoming this hurdle. The proposed Krylov MOR process Is demonstrated through Its application to the expedient broadband analysis of the impact of skin-effect loss on the transmission properties of a microstrip bandpass filter and the extraction of the propagation characteristics of a microstrip line on a dielectric substrate with frequency-dependent permittivity described by a Debye model.
