Abstract :
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).
