Abstract
In this investigation, scattering of laser light by polystyrene spheres has been examined. Our results demonstrate that certain multiple scattering data can be explained in terms of single scattering Mie theory. Multiple scattering can be interpreted as a succession of independent, single scattering events. Using this interpretation, we have derived an expression that yields the optimum particle size for maximum attenuation of laser light by particles suspended in a medium. The size is smaller than that predicted by the Mie theory alone. Results of this research have wide general application for all electromagnetic radiation and are particularly useful in determining optimum scattering materials and sizes for applications such as cavityless lasing, coherent backscatter, and localization of light.
