In this article, the angular distribution of the power radiated by magnetic or electric dipoles located at distance z 0 from a dielectric interface and oriented perpendicular to it is derived.Abstract:
We have derived analytical expressions for the angular distribution P(α) of the power radiated by magnetic or electric dipoles located at distance z0 from a dielectric interface and oriented perpendicular to it. For dipoles in the rarer medium very close to the interface, evanescent waves in the dipoles’ near field give rise to strong radiation into the denser medium. The resulting large maximum of P(α) shows characteristic differences for magnetic and electric dipoles when the relative refractive index of the two dielectrics is greater than √2. For dipoles lying on the interface a symmetry relation is established connecting the power distributions P(α) for the values n and 1/n of the relative refractive index.read more

Absorption and Emission of Evanescent Photons
TL;DR: In this paper, it is confirmed that absorption proceeds at a rate proportional to the second-order product of the complex field amplitude, whether the light field is homogeneous or evanescent, and that the emission process follows a reciprocity principle.
