3-D spectral domain Green´s function for arbitrarily multilayered dielectric structure

We present a full-wave analytical 3-D Green´s function in the spectral domain for arbitrarily multilayered dielectric media. The Green´s functions are two scalar potentials created by a horizontal element dipole, and two corresponding electromagnetic modes, the transverse magnetic and transverse electric modes to the normal direction of the layer plane. The analytical formulas in the spectral domain have simple form and hold for arbitrary number of the dielectric layers.
