  • Article

The optical theorem is generalized for the case of excitation of local structures by point sources. It is shown that an essential parameter, the Purcell factor, can be represented in analytical form. The results are generalized for the case of an interface between two semispaces. These results are of paramount impor tance for averaging of the coefficient of fluorescence amplification and the efficiency of an optical antenna by the position of an excitation source.
