Circuit-based model order reduction for EM-CAD

In this work, we focus on obtaining an accurate and reliable physical-based description of the Electromagnetics we are dealing with in order to carry out a fast and accurate computer-aided design. Appropriate Finite Element solution to time-harmonic Maxwell's equations in the frequency band of interest is involved and a reliable reduced-order model is obtained. Then, the electromagnetic behavior in the microwave device is rearranged and described in terms of circuit theory, giving rise to the coupling matrix representation of the original Maxwell problem.
