The equivalent volume-averaged light scattering behavior of randomly inhomogeneous dielectric spheres in the resonant range was studied by using finite-difference time-domain numerical experiments. It was observed that the results holds even for the extreme case in which the refractive index within an inhomogeneous sphere varies randomly over the range 1.0 to 2.0. The results demonstrated that the spectral dependence of the total scattering cross sections of randomly inhomogeneous dielectric spheres of sizes in the resonant range resemble their homogeneous counterparts that have a volume-averaged refractive index.
