Abstract
Evanescent waves generated by the scattering of polychromatic light using a spatially deterministic medium and their near-zone spectral properties, to the best of our knowledge, have not been addressed in the literature. On the basis of the first-order Born approximation, we formulate expressions for the near-zone scattered wave by assuming that the scattering potential of the medium is of the Gaussian profile. The dependence of the spectral shift on effective sizes of the scattering potential (ESSP) is shown using numerical simulations. It is indicated that the increase of either ESSP or near-field diffraction length can induce spectral shifts in scattered evanescent waves.
