Characterization of the radiative properties of porous media with diffuse isotropic reflecting interfaces
Аннотация
Absorption and scattering coefficients and phase function of porous media, considered as sets of dispersed radius
overlapping transparent spheres in an opaque solid phase and characterized by a diffuse isotropic reflection law at
the interface, have been determined for wavelengths small in regard of the typical structure length (i.e. by neglecting
diffraction). These coefficients have been, for porosity larger than 0.65, identified from Monte Carlo calculations
and fitted by linear functions versus the porosity. The phase function have been numerically calculated from Monte
Carlo calculations.
