Abstract : Recent work by S. Kagami and I. Fukai and also work by E. Tonye and H. Baudrand has demonstrated the application of the boundary element method for solving planar (two-dimensional) electromagnetic multiport scattering problems. The boundary element method is shown by these workers to be computationally more efficient than using finite element methods for two-dimensional cases. This report extends application of the boundary element method to the three-dimensional case, requiring a field vector integral equation formulation as opposed to the scalar field equation formulation used by the workers above. Computational details are discussed and numerical results are presented for a few simple test cases. The computational storage costs are shown to be proportional to the discontinuity volume raised to the four-thirds power.
