A hybrid single and dual simple layer boundary integral equation formulation for 3-D eddy currents

A hybrid single and dual simple layer Boundary Integral (BIE) formulation is proposed in this paper. The number of unknowns per node can be reduced to minimum, i.e. one, three or four unknowns respectively depending on various kinds of material interfaces. By using this formulation, the computer storage can be greatly reduced so that large and complex application problem may be numerically simulated. Numerical examples and an application are included.
