Abstract

The finite-difference time-domain (FDTD) numerical experiments were conducted and supporting analysis demonstrating that the spectral dependence of the total scattering cross-section of randomly inhomogeneous dielectric spheres of size in the resonant range closely resembles that of their homogeneous counterparts with a volume-averaged refractive index. This holds even for the extreme case where the index of refraction within the inhomogeneous sphere varies randomly over the range from 1.0 to 2.0 and internal inhomogeneities span up to 0.4 dielectric wavelength.
