我们报告了在具有反射壁的圆柱体中包含的聚苯乙烯球体的随机配置中的微波强度统计测量。随着样品厚度的增加，强度分布和强度相关函数随频移的测量揭示了从不相关到相关光子扩散的交叉。
We report measurements of microwave intensity statistics in random configurations of polystyrene spheres contained in a cylinder with reflecting walls. As the sample thickness increases measurements of the intensity distribution and the intensity correlation function with frequency shift reveal a crossover from uncorrelated to correlated photon diffusion.
