Abstract Random jammed dipole scatterers are natural composite and common byproducts of various chemical synthesis techniques. They often form complex aggregates with nontrivial correlations that influence the effective dielectric description of the medium. In this work, we investigate the packing dynamic of rectangular nanostructure under a close packing protocol and study its influence on the optical response of the medium. We show that the maximum packing densities, maximum scattering densities, and percolation threshold densities are all interconnected concepts that can be understood through the lens of Onsager’s exclusion area principle. The emerging positional and orientational correlations between the rectangular dipoles are studied, and various geometrical connections are drawn. The effective dielectric constants of the generated ensembles are then computed through the strong contrast expansion method, leading to several unintuitive results such as scattering suppression at maximum packing densities, as well as densities below the percolation threshold, and maximum scattering in between.

摘要 随机干扰偶极子散射体是各种化学合成技术的天然复合物和常见副产品。它们通常形成具有重要相关性的复杂聚集体，影响介质的有效介电描述。在这项工作中，我们研究了紧密堆积协议下矩形纳米结构的堆积动力学，并研究了其对介质光学响应的​​影响。我们表明，最大堆积密度、最大散射密度和渗透阈值密度都是相互关联的概念，可以通过 Onsager 的禁区原理来理解。研究了矩形偶极子之间出现的位置和方向相关性，并绘制了各种几何连接。
