使用严格的数值工具来计算一组二维粒子在二维干涉系统中的散射场，施加在这些粒子上的光力以及它们的运动，我们研究了可能与粒子形成接近光子晶体结构达到平衡的条件。结果表明，形成晶体的粒子数量是有限的，这种限制取决于粒子的参数和入射光的特性。特别注意了束缚现象，并表明初始捕获系统和光子晶体之间的周期变化与粒子和背景介质之间的光学指数对比呈线性关系。结果表明，在附加平面波照射下，晶体具有较强的鲁棒性。
Using rigorous numerical tools for computing the field scattered by a set of 2D particles immersed in a 2D system of interferences, the optical forces exerted on these particles, and their motions, we investigate the conditions in which it is possible to reach an equilibrium with particles forming a structure close to a photonic crystal. It is shown that the number of particles forming the crystal is limited, the limitation depending on the parameters of the particles and on the characteristics of the impinging light. Special attention is paid to the binding phenomenon and it is shown that the period change between the initial trapping system and the photonic crystal behaves linearly with respect to the optical index contrast between the particles and the background medium. Finally, it is shown that the crystal is robust when it is illuminated by an additional plane wave.
