用蒙特卡罗方法研究混浊介质光学性质的涨落

A study of the fluctuations of the optical properties of a turbid media through Monte Carlo method

Emiliano Terán-Bobadilla, Eugenio Méndez

摘要:

在这项工作中,我们提出了一个理论研究的光在非均匀系统中的传播与波动的光学性质。为了了解波动的后果,我们使用蒙特卡罗模拟进行数值计算与均匀和非均匀系统。我们考虑两种分布来表示非均匀介质:δ函数和指数负分布.结果表明,即使是有限矩分布,也可能需要大量的相互作用才能收敛到高斯统计.这在估计薄膜的光学性质时可能是重要的。

英文摘要:

In this work we present a theoretical study on the propagation of light in heterogeneous systems with fluctuating optical properties. To understand the consequences of the fluctuations we perform numerical calculations with uniform and non uniforms systems using Monte Carlo simulations. We consider two distributions to represent a non-uniform medium: delta function and an exponential negative distributions.The results show that even with finite moments distributions, may require a large number of interactions for a convergence towards Gaussian statistics. This can be important when estimating the optical properties of thin films.
