Abstract: We review the difficulties of a modal approach when modeling a Reverberation Chamber (RC) by the Finite Element Method (FEM). The numerical challenge is due to the large scale problem involved by the over-dimensioned cavity. Moreover, the field singularity on the stirrer has to be captured by the FEM. First the following issues are discussed: existence of nullfrequency solutions, convergence rate for h and p adaption, and formulation type in E or H field. Then the modal analysis is compared to the classical ha…
