从稳态和时域两个方面研究了光在各向异性随机介质中的传播。各向异性扩散方程的解决方案进行比较，通过蒙特卡罗方法得到的结果。与迄今为止的报道相反，我们发现，即使在“扩散制度”的各向异性扩散方程不正确描述光在各向异性随机介质中的传播。
Light propagation in anisotropic random media is studied in the steady-state and time domains. Solutions of the anisotropic diffusion equation are compared to results obtained by the Monte Carlo method. Contrary to what has been reported so far, we find that even in the "diffusive regime" the anisotropic diffusion equation does not describe correctly the light propagation in anisotropic random media.
