Dipole Radiation in Scattering Environments

So far we have considered surfaces and nanoparticles under the illumination of a plane-wave and a dipole radiation in the free-space. In molecular plasmonics instead we have to deal with the 

Let s consider an emitting point-like dipole located at Tq. Then according to Sec. 1.6 and Eq. (1.215) the total electric field at Tq will be
