  • Abstract
    The mode spectra of individual electromagnetic vector potential finite elements are studied in detail. Theoretical spectra are deduced from the general properties of vector fields and the specific shape functions used in particular elements. Results are compared with spectra calculated using standard isoparametric tetrahedron and hexahedron elements. It is shown that spurious shear modes are present in addition to the more familiar spurious divergence and translation modes
