Energy Conservation: A Test for Scattering Approximations

  • Charles Acquista

We explore the roles of the extinction theorem and energy conservation in obtaining the scattering and absorption cross sections for several light scattering approximations. We show that the Rayleigh, Rayleigh-Gans, Anomalous Diffraction, Geometrical Optics, and Shifrin approximations all lead to reasonable values of the cross sections, while the Modified Mie approximation does not. Further examination of the Modified Mie approximation for the ensembles of non-spherical particles reveals additional problems with that method.
