Abstract
The numeric dispersion error of the 3D envelope-finite element (EVFE) method is analyzed with several examples. The results show that the EVFE method has a much lower dispersion error compared to the unconditionally stable finite element time domain (FETD) method. Furthermore, in the analysis of high Q structures, such as resonators or filters, the EVFE technique can obtain the resonator frequency or frequency response, not only efficiently, but also accurately.
