A circuit description of the electromagnetic behavior in microwave filters by means of the data provided by FEM analysis in the frequency band of interest is detailed. Loewner matrix approach is used to carry out a tangential interpolation of the simulation data, giving rise to a linear dynamical system description fitting the simulation results. The FEM solver is then used as a black box unlike other...
A comparison between modelling and simulation methods in regard to model order reduction (MOR) in finite element (FE) simulation tools is presented. Two main software tools are taken into consideration: ANSYS Multiphysics 11 with its extension MOR for ANSYS 2.55 and COMSOL Multiphysics 3.5a with a model order reduction interface to MATLAB/Simulink. The results achived with both software packages are...
