N2 - Scattering of electromagnetic waves by a composite has a significant impact on its perceived quality, and has been used as a nondestructive measurement surrogate for the health of polymeric composites. Electromagnetic wave scattering is used to estimate flaw size distribution, used as input in calculating fracture failure due to stress concentration. Light scattering from the surface (specular) and reemerging from within a coating (diffuse) is a function of wavelength and the weighted integral of these terms gives the gloss and color of a material, particularly relevant for coatings. Monte Carlo ray tracing is a stochastic computational method used to calculate the transport of electromagnetic waves, with a finite element solution of nanoparticle scattering used to generate a surface source for particles below the geometric optics limit. A 3-dimensional Monte Carlo/FEA model is being developed, capable of analyzing scattering by composites containing scatterers comparable to or smaller than the wavelength of incident light.
