Аннотация

We study in this article the emission spectrum of a plane semi-infinite medium. We show that this spectrum displays remarkable differences depending on whether it is calculated in the near or in the far zones. These differences are particularly striking when the material support surface waves. We propose a novel application of near-field spectroscopy to retrieve the dielectric constant at a submicronic scale.
