The layered medium Green's function—A new look

This paper describes an alternate method to formulate the layered medium Green's function suitable for computational electromagnetics. The Green's function is symmetrized so that the reciprocity theorem becomes obvious. Also, the vector differential operators are explicit so that they can be transferred to operate on the basis function and the testing function, as is often done in the method of moments. This alternative formulation of the layered medium Green's function makes it simple to integrate with other computational electromagnetic methods.
