摘要

我们使用超表面数值演示了粒子的捕获和旋转，超表面是通过将纳米腔排列成右旋阿基米德螺旋而形成的。在90°线性偏振光束的激发下，在螺旋的中心形成了聚焦的表面等离子体激元（SPP）场，粒子可以被该场捕获。在−45°线偏振光束的激发下，形成了携带轨道角动量的涡旋SPP场，粒子可以在涡旋场处被捕获并沿顺时针方向旋转。

Trapping and rotation of microparticles using a metasurface exciting by linearly polarized beam

We numerically demonstrate trapping and rotation of particles using a metasurface formed by arranging nanocavities as a right-handed Archimedes’ spiral. Excited by a 90° linearly polarized beam, a focused surface plasmon polariton (SPP) field is formed at the center of the spiral, and the particle can be trapped by the field. While excited by −45° linearly polarized beams, a vortex SPP field carrying orbital angular momentum is formed, and the particles can be trapped and rotated in the clockwise direction at the vortex field.
