Abstract
Cataloged from PDF version of article.Spatial-domain Green’s functions for multilayer,
planar geometries are cast into closed forms with two-level approximation
of the spectral-domain representation of the Green’s
functions. This approach is very robust and much faster compared
to the original one-level approximation. Moreover, il does
not require the investigation of the spectral-domain behavior of
the Green’s functions in advance to decide on the parameters
of the approximation technique, and it can be applied to any
component of the dyadic Green’s function with the same ease
