This paper investigates optical forces on absorptive Rayleigh particles produced by a nondiffracting microstructured vectorial beam (micrometer Frozen Wave) designed from a continuous superposition of first-order Bessel beams, very adaptive to highly nonparaxial conditions. Carrying a non null topological charge and possessing a vector nature, these beams have both orbit and spin angular momentum. Thus, this paper aims to investigate the possibility of setting a Rayleigh particle to follow a circular or elliptical trajectory by these beams. Since energy considerations are also taken into account, optical forces can be conveniently expressed in femtonewtons. Numerical results demonstrate that the micrometer Frozen Wave is able to produce full three-dimensional optical trapping points, thus allowing the manipulation of several particles simultaneously. Additionally, those beams with circular (elliptical) polarization states are capable of setting the particle to follow a circular (elliptical) orbit around the optical axis.

本文研究了由一阶贝塞尔光束的连续叠加设计的非衍射微结构矢量光束（微米冻结波）产生的吸收性瑞利粒子上的光学力，该光束非常适合于高度非傍轴条件。这些光束携带非零拓扑电荷并具有矢量性质，具有轨道角动量和自旋角动量。因此，本文旨在研究通过这些光束将瑞利粒子设置为遵循圆形或椭圆形轨迹的可能性。由于还考虑了能量问题，因此可以方便地以毫微牛顿表示光力。数值结果表明，千分尺冻结波能够产生完整的三维光学捕获点，因此可以同时处理多个粒子。另外，那些具有圆形（椭圆）偏振态的光束能够将粒子设置为遵循围绕光轴的圆形（椭圆）轨道。
