A generalized random medium is introduced of which the effective radius and the correlation length are assumed to depend on the wavelength of the incident light. The generalized Stokes parameters of a random electromagnetic beam are employed to characterize the statistical properties of the far-zone scattered field generated by the introduced random medium. It is shown that the dependence of the effective radius and the correlation length of a medium on the wavelength can affect the behaviors of the intensity, coherence and polarization of the scattered field. Besides, the distributions of the scattered field are found to have many differences between the situations of medium-led modulation and beam-led modulation.
