摘要：

The natural frequencies of a hollow, perfectly conducting sphere with a circular aperture are calculated. The trajectories of the poles in the complex plane reveal an intriguing behavior which depends on whether the poles originate from internal or external sphere resonances. It is found that the modal degeneracy of the complete sphere is removed by the addition of the aperture.
