Abstract
This paper investigates the interior resonance problem with the help of a three-dimensional FEM/BEM-hybrid approach basing on the electric field integral equation (EFIE) and edge finite elements in terms of the electric field strength qq. It is demonstrated that the corruptions due to interior resonances mainly depend on the numerical accuracy of the implementations of the participated field calculation techniques. This result clearly explains that the interior resonance problem of the FEM is not significant because the FEM matrix elements can be calculated analytically (machine accuracy). The extremely narrowband corruptions can effectively be suppressed by the introduction of very small losses that do not influence the results in the lossless case.
