Constructive interference between coherent waves traveling time-reversed paths in a random medium gives rise to the enhancement of light scattering observed in directions close to backscattering. This phenomenon is known as enhanced backscattering (EBS).
According to diffusion theory, the angular width of an EBS cone is proportional to the ratio of the wavelength of light λ to the transport mean-free-path length
