These equations represent a modification of the Kubelka-Munk equations, or radiative transfer. Our modification accounts for wave interference (e.g., localization), which is neglected in radiative transfer. We numerically solve the modified Kubelka-Munk equations and compare the results to radiative transfer as well as to simulations of the wave equation with randomly located thin layers.8 pages, 3 figures (2 figures with 4 panels each), under submission to Phys Rev EMesoscale and Nanoscale PhysicsStatistical Mechanicstext
