Abstract :
The resonance frequencies for an arbitrary-shaped cavity are determined using an approach whereby the known eigenmodes of a canonical cavity are employed to formulate the eigenvalue problem. Although the approach is originally developed for three-dimensional problems, using it for two-dimensional geometries will result in accurate estimation of the cut-off frequencies of waveguides with arbitrary-shaped cross-section.
