The Mie solution to the scattering of electromagnetic waves by spherical particles has been examined using COMSOL Multiphysics®. The results assume elastic scattering only and do not include Brillouin or Raman scattering. The nature of the interaction has been considered for materials with three different properties: metallic, magnetic and dielectric. The solutions provide details of the absorption, scattering, extinction, pressure cross-sections, back-scattering and radiation force exerted on the particle by an incident plane wave. The results are compared with the Mie analytical solution and show good agreement with the Mie solution.
