“…However, in fact, the electric vector of light may give rise to polarization of the scattering medium, and the polarization will bring about a change of the dielectric sus-ceptibility and the refractive index of the scattering medium [18,27]. Therefore, some previous papers have been published to discuss the issue of the properties of the far-zone scattered field that involve the effects of the wavelength of the incident field on the scattering media [18,28]. However, as far as we know, almost all the publications on this issue are based on isotropic medium model with spectral dependence.…”
