Paper Abstract

We demonstrate theoretically that for polychromatic incident light of Gaussian spectrum, a dipole radiates with a redshifted spectrum. The degree of the shift depends on the radiation distance. The shift disappears in far field limit. These spectral changes are not caused by dispersive optical response of the source, nor stemming from correlations in distributions of source or scattering medium. Therefore, the demonstrated spectral changes are due to the nearness of the observation point. In other words, one states that the near field spectra, in general, bear a redshift with respect to the far field spectra.
