Enhancement of the backscattered intensity from fractal aggregates

Abstract Comparative measurements were conducted for the backscattered intensities of light from uniform random and fractal aggregated media. Different features are found for the backscattered intensity peak shapes. A crossover between the θ1−D and θ−2 dependences of the backscattered intensity occurs in the case of fractal aggregated medium, where D indicates the fractal dimension.
