Scattering of Light from Rough Surfaces, the Limits of Validity of Geometric Optics Approximation Method
The geometric optics approximation(GOA)for predicting wave scattering from rough surfaces is developed.The GOA consists of ray tracing the energy incident on a rough surface until it leaves the surface after having incurred multiple rebounds.The effects of the direction of incident light and optical properties of rough surfaces on the scattering and the backscattering of light are presented.For one-dimensional rough surfaces,the GOA is quantified by comparisons with the exact electromagnetic theory calculations.Shadowing affects and the multiple scattering are studied for Gaussian random rough surfaces.The regions of validity of the approximation method for TE and TM polarization are quantified.For dielectric rough surfaces,the integral method(IM)is used to determine the domains of validity of the GOA.Using that method represents a significant reduction in computational time and memory.
