Abstract
For spheres of arbitrary radius and complex index of refraction , we identify a new parameter that indicates when the imaginary part seriously affects the scattering by a sphere. The parameter is , where is the wave vector magnitude, such that when grows larger than one, the scattering is affected and, when , the effects saturate. The effects are uncovered and demonstrated with -space analysis. The physical basis for lies in the fact that it is the ratio of the radius to the optical skin depth.
