我们报告了一个戏剧性的增强的横向光学力诱导的电极化瑞利粒子附近的双曲线和极端各向异性超颖表面下简单的平面波照明。这种增强是通过由这些结构提供的增加的态密度和由粒子获得的面外极化自旋之间的相互作用实现的。由此产生的巨大的横向力出现在一个广泛的频率范围内，并可能为路由，捕获和组装纳米粒子开辟前所未有的场所。
We report a dramatic enhancement of the lateral optical forces induced on electrically polarizable Rayleigh particles near hyperbolic and extremely anisotropic metasurfaces under simple plane wave illumination. Such enhancement is enabled by the interplay between the increased density of states provided by these structures and the out-of-plane polarization spin acquired by the particle. The resulting giant lateral forces appear over a broad frequency range and may open unprecedented venues for routing, trapping, and assembling nanoparticles.
