Abstract
The possibility of an alternative approach for particle scattering is presented. In this approach, a correlation function is derived that describes the permittivity fluctuations due to sharp gradients at the boundary of a particle and the particle distributions to the level of pair correlation. Once such a correlation function is available, some conceptions of turbulence scattering become eligible for application. Analytic results in the cases when the permittivity contrast is weak or the particle size is small are shown to be in good agreement with the corresponding ones that are obtained by using the conventional approach. This new approach is expected to be useful in solving some difficult problems in particle scattering systems such as computing the higher moments and temporal behavior, at least in the extreme cases mentioned above.
