Replacement of Ensemble Averaging by the Use of a Broadband Source in Scattering of Light from a One-Dimensional Randomly Rough Interface between Two Dielectric Media

Figure 4

The quantities and obtained for a vacuum-glass system [ and ] plotted on semilogarithmic scales for ν = p [Figure 4(a)] and ν = s [Figure 4(c)]. Comparison of the mean differential reflection coefficients obtained by either a rigorous simulation approach or on the basis of phase perturbation theory (PPT) for p-polarized (Figure 4(b)) or s-polarized (Figure 4(d)) illumination. All ensemble averaged quantities were obtained on the basis of N_p = 10,000 realizations of the interface profile function. The remaining parameters are identical to those of Figure 2.
