论文摘要
安德森本地化标志着无序系统中扩散波传播的停止。尽管在过去40年中进行了广泛的研究，但安德森在三个维度上将光定位的定位仍然难以捉摸，导致了其存在的问题。有限差分时间域计算的最新速度速度加速使我们能够对具有前所未有的维度和折射率对比的完全无序的3D系统中的光传输进行蛮力数值模拟。我们证明了在金属球的随机堆积中对矢量电磁波的三维定位，与缺乏与10个基本研究相关的广泛基本研究的折光指数对比的介电球的局部性鲜明对比。
Anderson localization marks a halt of diffusive wave propagation in disordered systems. Despite extensive studies over the past 40 years, Anderson localization of light in three dimensions has remained elusive, leading to the question of its very existence. Recent orders-of-magnitude speed-up of finite-difference time-domain calculations allows us to conduct brute-force numerical simulations of light transport in fully disordered 3D systems with unprecedented dimension and refractive index contrast. We demonstrate three-dimensional localization of vector electromagnetic waves in random packings of metallic spheres, in sharp contrast to the absence of localization for dielectric spheres with a refractive index contrast up to 10. Our work opens a wide range of avenues in both fundamental research related to Anderson localization and potential applications using 3D localized light.
