A rigorous theory of finding radiation in the far zone of an elementary dipole located at the boundary or inside a plane-layered structure is considered. A particular case of radiation from an elementary dipole located at the free boundary of one film is considered in detail, an effective method for finding the radiation field in the far zone in the surrounding half-spaces is proposed. Directional patterns of point emitters (molecules, nanostructures) located on the free surface of a metal film in the Kretschman scheme and having an induced dipole moment directed parallel or perpendicular to the film surface are obtained.
