Focusing in on Particle Shape

  • J. Mayo Greenberg

Abstract

While it is recognized that naturally occurring scattering particles are not always perfect spheres, nevertheless a vast amount of theoretical calculations have been made for perfect spheres. Why is this? There are two obvious and very important justifications: (1) many of the qualitative and even quantitative characteristics of particle scattering are adequately represented by equivalent spheres — where equivalence may have varying definitions in applications to different scattering properties, and (2) Mie theory calculations have been easy to perform even before the advent of modern high speed computers — dating back to the 1930’s.
