Light Scattering by Composite Rough Surfaces

A novel optical diffuser based on polymer micro-balls-filled nematic liquid crystal composite film

“…[38][39][40] In 1908, G. Mie provided a solution for the spherical wave function, which accurately predicts sphere scattering for all sizes of spheres. 41,42 The Rayleigh approximation can be applied when the size of the particle is smaller than the wavelength of the incident light. [43][44][45] Meeten et al considered the results for isotropic and anisotropic spherical droplets and observed that the Rayleigh-Gans approximation and anomalous diffraction approximation can be applied for anisotropic spheres with a mean refractive index close to that of the polymer.…”

“…[46][47][48][49][50] The basic theories for LC droplets were developed by Stein and Rhodes, Meeten and Navard, Zumer, Whitehead, Yang, Montgomery and others. [36][37][38][39][40][41][42][43][44][45][46][47][48][49][50] S. Zumer theoretically studied the light scattering from a single spherical birefringent droplet. For LC droplets that are much smaller than the wavelength of the light, the Rayleigh-Gans approximation describes the scattering, while for LC droplets that are comparable in size to the incident light wavelength, the anomalous diffraction approach is more appropriate.…”
