Light Scattering By Polystyrene Spheres On A Mirror

Three models have been developed to describe light scattering from a sphere positioned on a mirror. The actual system is modeled as a two-sphere system consisting of a real and an imaginary sphere. Light scattering from each sphere is assumed to follow Mie theory. No further interaction is assumed between the sphere and the mirror. The models differ in their consideration of the interaction of scattered fields from the spheres. The results of the models are compared with experimental values with the size parameter 4.88 and 7.00 with s- and p-polarization. The comparison indicates that a best fit can be obtained by assuming the two spheres are coherent light sources with a phase difference ofπ.
