We present an extension of the coupled dipole approximation technique to model optical properties of large-scale slabs of homogeneous and inhomogeneous materials. This method is based on a modification of the Green's function to take into account the interaction between dipoles located at arbitrary distances within the slab. This method allows modeling of various aspects of the structural morphology of composite materials, including component size and spatial distribution as well as surface roughness effects. Our procedure provides an adequate description of far-field optical properties such as the specular and diffuse reflection of light.
我们提出了一种耦合偶极近似技术的扩展方法，用于对均匀和非均匀材料的大规模平板的光学特性进行建模。该方法基于对格林函数的修正，以考虑平板内任意距离处偶极子之间的相互作用。这种方法能够对复合材料结构形态的各个方面进行建模，包括组分尺寸、空间分布以及表面粗糙度效应。我们的方法能够充分描述远场光学特性，如光的镜面反射和漫反射。
