The scattering medium consists of various volume fraction of particles which are either 0.22 μm or 0.494 μm in diameter and which are suspended in filtered distilled water. A comparision is made of the intensity distribution of the horizontally and vertically polarized radiation side-scattered from small particles. The experimental results indicate that the intensity of horizontal polarization for the small particles is much larger than that of the larger particles. This phenomenon is exactly the reverse of the vertical polarization cases.
