Singularity/integral equation method development for 3-D electromagnetic field calculation

A new integral equation formulation for solving general 3-D electromagnetic field problems using the method of singularities is briefly described. Detailed expressions of integral equations for axially symmetrical open and confined field cases derived from the basic general 3-D formula are given. Mathematical singularities encountered in the equations are analytically removed and an iterative solution procedure is adapted. Numerical results obtained for several test cases during the developmental stage of this method are presented.
