摘要：

A modification in the implementation of the finite element-boundary integral method is proposed for eliminating the interior cavity resonances. It is demonstrated that by using the scattered rather than the total field as the system variable, and by introducing a small loss in the propagation constant associated with the boundary integral equation, internal resonance effects are eliminated. Results are presented for two-dimensional problems with the finite element mesh terminated on a circular enclosure.
