Millimeter-wave discontinuity circuit models have been developed on the basis of systematic full-wave data generated by a rigorous numerical approach. The applied physics-related and topology-sensitive modeling concept is new and extends previous quasi-static descriptions into dynamic ones including parasitic wave coupling and package resonances. The dynamic models developed for open end, gap, step, bend, and T-junction are valid below and above cutoff of the dominant package mode. They make it possible to predict package resonances and their effect on component behavior. Agreement with the respective field-theoretical simulations is good, which verifies that the proposed modeling approach indeed incorporates the dominant physical mechanism.
