Studying the physical mechanisms involved can offer practical insight for the control or harvesting of radiant energy. Here the polarizability of radially inhomogeneous spheres is determined, for three analytically solvable cases. These exact solutions reveal particular scattering peculiarities that can be used as the ``smoking gun'' for recognizing particular types of inhomogeneities, and present avenues for controlling or harvesting light via single inclusions or surface/bulk composite materials.
