Аннотация:The scattering of the field of an electric dipole by a local penetrable body in the presence of a transparent halfspace is considered. A relation is obtained that is similar to the optical theorem in the case of an incident plane wave. With this generalization, the fluorescence enhancement factor or the efficiency of
an optical antenna can be calculated without computing the absorbed energy, which considerably reduces the
computational costs.
