## Abstract Many different procedures have been proposed for the finite element analysis of dielectricβloaded waveguiding structures. However, most of these approaches are unreliable because of the appearance of spurious modes. Mixedβorder covariant projection finite elements have been shown to eli

The eigenmodes in electromagnetic cavities, loaded with arbitrarily shaped dielectric materials, are computed by the edge element method. The computation shows that the well known 'spurious modes' no longer appear. Formulae are given and verified so that the number of zero eigenvalues, which come fr
