Abstract :
The presented stability analysis has been implemented into the EM-FDTD package SEMCAD X, and its functionality and reliability have been tested with use cases from contemporary research projects. It has been found that the developed stability analysis can reliably assess the stability of a simulation containing arbitrarily distributed dispersive media. Moreover, the novel subcell averaging technique is shown save significant computer resources while maintaining very accurate results.
