Abstract
A new formulation is described which combines the most robust attributes of the volume finite element and surface
integral equation approaches to electromagnetic boundary value solutions. The result is a numerical technique which may
be applied to scatte ring problems involving configurations having metallic surfaces and inhomogeneous penetrable mate rial
situated in open spatial regions. This is accomplished by way of coupling internal region finite element modal field solutions
to equivalent currents on the surrounding boundary surface through an appropriate surface integral equation. The method
is demonstrated for the special case of scattering by axisymmetric inhomogeneous penetrable objects. Example numerical
calculations are presented for validation of the procedure and potential problem areas are discussed.
