LOW FREQUENCY SOLUTION OF THREEDIMENSIONAL SCATTERING PROBLEMS.
MICHIGAN UNIV ANN ARBOR RADIATION LAB
A deficiency is pointed out in Stevensons method of reducing the solution of electromagnetic scattering problems to a succession of standard potential problems whose solutions determine terms in the low frequency expansion of the scattered field. An alternate approach is presented, for perfectly conducting scatterers, which not only removes the difficulty but also is simpler and more explicit than Stevensons method. The details of the analogous, though simpler, scalar scattering problems are also presented.
