We present an innovative approach for the simultaneous agile manipulation of high-refractive-index (HRI) and low-refractive-index (LRI) particles. Our method involves introducing a dual-curvilinear optical vortex beam (DC-OVB) generated by superimposing a pair of curved beams: HRI and LRI particles are controlled by the bright curve and the dark channel between the two curves, respectively. The proposed DC-OVB provides customizable motion paths and velocities for both LRI and HRI particles. Each curve of the DC-OVB can support a distinct orbital flow density (OFD), enabling the application of torques to HRI and LRI particles, guiding them to orbit along specified trajectories and prompting them to execute various curvilinear motions simultaneously, including curvilinear movement, revolution, and rotation.

双曲线光束能够对高折射率和低折射率粒子进行可调谐操纵


我们提出了一种同时敏捷操纵高折射率（HRI）和低折射率（LRI）粒子的创新方法。我们的方法涉及引入通过叠加一对弯曲光束产生的双曲线光学涡旋光束（DC-OVB）：HRI 和 LRI 粒子分别由亮曲线和两条曲线之间的暗通道控制。所提出的 DC-OVB 为 LRI 和 HRI 粒子提供可定制的运动路径和速度。 DC-OVB的每条曲线都可以支持不同的轨道流密度（OFD），从而能够对HRI和LRI粒子施加扭矩，引导它们沿着指定的轨迹进入轨道，并促使它们同时执行各种曲线运动，包括曲线运动、公转、自转。
