ELECTROMAGNETIC SCATTERING BY RANDOMLY ORIENTED BISPHERES - COMPARISON OF THEORY AND EXPERIMENT AND BENCHMARK CALCULATIONS

A good quantitative agreement is found between laboratory measurements of the scattering matrix for a randomly oriented latex bisphere with touching, nearly identical micron-sized components and theoretical com putations using the T-matrix method. Our comparison of theory and expe riment provides an additional validation of the computational method a nd also demonstrates that polarization measurements of light scatterin g can be employed as an accurate particle sizing technique. The T-matr ix method is used to tabulate light scattering properties of two diffe rent kinds of randomly oriented bispheres with touching and separated components. Because of high accuracy, our computations can serve as be nchmarks.
