Abstract

Enhanced backscattering from random fractal media is investigated by means of Monte Carlo simulations based on a randomized Menger sponge model of the media. Dependence of the coherent peak on the fractal dimension D is obtained for 1.5 less than or equal to D less than or equal to 2.79, and it is found that the slope of the peak shoulder in a log-log plot increases with D until D equals 2.5 and then decreases for a further increase in D. This behavior is elucidated on the basis of probabilities of the scattering free path, the number of scattering in a multiple scattering path, and the separation of two end particles in a scattering path.
