摘要：

A higher order regularization of the multilayered mixed-potential Green's functions, based on enhanced effective-media extractions, is presented. Singularities in the source point, both of the Green's function and of its derivatives up to the second order, are fully removed. The regular kernel obtained permits the effective implementation of near-field interpolation schemes with application to the solution of electromagnetics problems by the method of moments (MoM).
