Abstract:
The intensity temporal profiles of diffusive light propagation in highly concentrated (up to volume fraction phi similar to 0.55) dispersions measured by 100-fs laser pulses showed an increase in transport scattering mean free path above a critical concentration. This observation confirms the previous theoretical predictions of enhanced transmission at high particle concentrations due to correlated scattering. The correlation effects are accounted for by incorporating a hard sphere Percus-Yevick static structure factor into the prediction of transport mean free path. (C) 1998 Optical Society of America.
