Light Standing-Waves in Aggregates of Amorphous Carbon Grains

摘要: The phenomenon of localization light by disorder is a result the interference electromagnetic waves scattered random medium across which they propagate [1]. Up to now, only precursive effects optical in form an enhanced backscattering visible aqueus suspension polystyrene spheres have been observed [2]. One crucial problem measure strong that length for classical quite large, compared quantum particle. A recent [3] shows most important mechanism needed reduce whose index refraction very often changes randomly from small value large one. This possible if distribution probability function ρ(n), describing n, uniform between (1,1+δ 1) U(1+W-δ 2,1+W), where W measures degree n and δ 1,δ 2 are widths two distributions. relation three parameters 2, defining ρ(n) description propagation medium. limit W=δ 1 + corresponds simply allows fluctuations around some value. In this case, regime will be difficult reach.
