Finite-size effect in light transmission through highly forward scattering media at grazing angles
Abstract:
We present a theoretical study of light transmission through a disordered medium with large (compared to the light wavelength) inhomogeneities. Both numerical integration and analytic treatments of the radiative transfer equation are performed. An effect of the single-scattering phase function on the total transmittance is found in a subdiffusion thickness range. The effect reveals itself at grazing angles of incidence and originates from small-angle multiple scattering of light. A simple analytic formula for the total transmittance is derived. Our results are in good agreement with data of independent numerical calculations.
