Numerical simulation of the electromagnetic wave reflection from 2D random semi-infinite strongly scattering media

Light scattering in disordered media plays an important role in various areas of applied science from biophysics to astronomy. In this paper we study two approaches to calculate scattering properties of semi-infinite densely packed media with high contrast and wavelength scale inhomogeneities by combining the Fourier Modal Method and the super-cell approach. Our work reveals capabilities to attain ensemble averaged solutions for the Maxwell's equations in complex media, and demonstrated numerical convergence supports the consistency of the considered approaches.
