Mishchenko, M.I., L. Liu, and D.W. Mackowski, 2014: Morphology-dependent resonances of spherical droplets with numerous microscopic inclusions. Opt. Lett., 39, no. 6, 1701-1704, doi:10.1364/OL.39.001701.

We use the recently extended superposition T-matrix method to study the behavior of a sharp Lorenz-Mie resonance upon filling a spherical micrometer-sized droplet with tens and hundreds of randomly positioned microscopic inclusions. We show that as the number of inclusions increases, the extinction cross-section peak and the sharp asymmetry-parameter minimum become suppressed, widen, and move toward smaller droplet size parameters, while ratios of diagonal elements of the scattering matrix exhibit sharp angular features indicative of a distinctly nonspherical particle. Our results highlight the limitedness of the concept of an effective refractive index of an inhomogeneous spherical particle.
