Abstract :
The issue of passivity in the macromodeling of electromagnetic components and subsystems is examined. In particular, the way loss of passivity may occur during the numerical characterization of the component/subsystem is investigated in the context of discrete modeling methods. In addition, the way various types of model order reduction techniques impact the passivity of the generated macromodel is considered. Finally, ways to ensure passivity during the numerical modeling and macromodel generation of an electromagnetic subsystem are identified
