Abstract
The far-zone behavior of polychromatic light waves on scattering from an isotropic semi-soft-boundary medium with spectral dependence is considered, and both spectral shifts and spectral switches of the scattered field have been discussed. It is shown that the spectral behavior of the far-zone scattered field is influenced by the structural function width of the dielectric susceptibility of the scattering medium. In particular, the structural function width of the dielectric susceptibility of the scattering medium plays an important role in the direction at which the spectral switch occurs. These results may have potential applications in areas such as the inverse scattering problem.
