Abstract

Intensity enhancement in the multiple scattering from highly disordered media is produced in the direction of retroreflection, and is called weak localization of light or enhanced backscattering¹⁾. It is well known for the scattering from uniform random media that the intensity peak decreases in inverse proportion to the backscattering angle²⁾. However, it was experimentally shown that a decreasing behavior is broken for a random medium with a fractal structure produced by the aggregation of particles³⁾. Due to the difficulty in controlling the fractal dimension of scattering media, there is no quantitative study on the enhanced backscattering produced from fractal media. In this report, we investigate quantitatively the dependence of the intensity peak on the fractal dimension (cluster dimension) by using Monte Carlo simulations.
