Fast parameter sweeps for the calculation of S-parameters in electromagnetic field simulations

The Maxwell equations have in general no analytical solution and are therefore often discretized in the space variables leading to a system of differential equations constituting the Maxwell Grid Equations. The discretization method used here is the Finite Integration Theory (FIT). In electromagnetic field computations a model often needs to be simulated many times with varying parameters. As the systems consisting of the Maxwell Grid Equations can be very large, simplified models which capture the main features of the original model are then successfully used instead of the original models. These models are obtained by means of model order reduction (MOR) methods. Parametric MOR (PMOR) methods respect also parametric variations.
