论文摘要
我们通过结合随机粗糙表面和体积介电波动的系统研究光散射。我们介绍了一个通用模型，包括表面和体积障碍之间的相关性，并研究单个散射方法中的散射特性。我们确定了表面和体积障碍表征的长度尺度的不同表面和体积的不同状态。对于不相关的疾病，我们讨论了每种疾病来源的极化响应，并展示了如何使用极化测量来分离总测量的扩散散射强度中的表面和体积贡献。对于相关系统，我们确定了两种体积障碍的构型，它们分别弱或强烈地通过表面体积互相关的表面散射。我们说明了这些对不同构型的影响，这些构型在扩散散射的强度中表现出干扰模式，这对于复杂系统的表征或通过工程化表面量相关性的程度而言，这可能是对复杂系统的表征或光学组件设计的感兴趣。
We study light scattering by systems combining randomly rough surface and volume dielectric fluctuations. We introduce a general model including correlations between surface and volume disorders, and we study the scattering properties within a single scattering approach. We identify different regimes of surface and volume dominated scattering depending on length scales characterizing the surface and volume disorders. For uncorrelated disorders, we discuss the polarization response of each source of disorder, and show how polarimetric measurements can be used to separate the surface and volume contributions in the total measured diffusely scattered intensity. For correlated systems, we identify two configurations of volume disorder which, respectively, couple weakly or strongly to surface scattering via surface-volume cross-correlations. We illustrate these effects on different configurations exhibiting interference patterns in the diffusely scattered intensity, which may be of interest for the characterization of complex systems or for the design of optical components by engineering the degree of surface-volume correlations.
