WebVector Rayleigh-Sommerfeld (VRS). The VRS method [Laser Phys. Lett. 10(6) 065004 (2013)] allows to propagate (Ex,Ey,Ez) fields offering the advantage of significant reduction in computation, from flat diffractive elements (Thin Element Approximation) with full control of polarization. It addresses simultaneously both longitudinal polarization. WebJan 31, 2005 · Sums of Rayleigh random variables occur extensively in wireless communications.

Rayleigh–Gans approximation, also known as Rayleigh–Gans–Debye approximation and Rayleigh–Gans–Born approximation, is an approximate solution to light scattering by optically soft particles. Optical softness implies that the relative refractive index of particle is close to that of the surrounding medium. The approximation holds for particles of arbitrary shape that are relatively small but can be larger than Rayleigh scattering limits.
