Correlation of particle length and radius: a new model for flux noise in particulate media

Several theoretical models for predicting the flux noise of particulate media are reviewed, and a statistical model that stresses the correlation between particle radius and particle length is proposed. The predictions from this model are much more wavelength-dependent than in previous models. This dependence is already exhibited at wavelengths that are an order of magnitude larger than median particle length. The model is empirically supported by particle-size measurements.>
