摘要：

We propose a simple and efficient method that uses a single focused hybrid vector beam to confine metallic Rayleigh particles at multiple positions. We study the force mechanisms of multiple trapping by analyzing the gradient and scattering forces. It is observed that the wavelength and topological charges of the hybrid vector beam regulate the trapping positions and number of optical trap sites. The proposed method can be implemented easily in three-dimensional space, and it facilitates both trapping and organization of particles. Thus, it can provide an effective and controllable means for nanoparticle manipulation.
