This sequence of papers presents an analytical closed form for the Green's function of an
infinite slot printed between two different homogeneous dielectrics. This first part is devoted
to the derivation of the slot magnetic current and to the discussion of the relevant physical
implications. The Fourier spectrum of the magnetic current is derived by solving in analytical
form, under small width approximation, the integral equation (IE) representing the continuity
of the magnetic field trough the slot axis. The accuracy of the result is validated trough a fine …

This second part of a two-paper sequence deals with the uniform asymptotic description of
the Green's function of an infinite slot printed between two different homogeneous dielectric
media. Starting from the magnetic current derived in Part I, the dyadic Green's function is first
formulated in integral form in both spectral and spatial domains; next, the asymptotic solution
for the vector potential is evaluated asymptotically. The asymptotic ray-field is structured in
three contributions: a spherical wave radiated by the source (space wave), a conical leaky …
