Abstract :
The eigenvalues of a cavity resonator are computed using edge-based elements, and it is shown that these elements offer significant improvements in accuracy, in addition to being suitable for modeling arbitrarily shaped inhomogeneous regions. A performance comparison between the edge-based tetrahedra and rectangular brick elements is also carried out
