| 摘 要： | 文章论述了利用类贝塞尔光束产生光俘获的特点,即在最大准直范围(Zmax)内能实现多个粒子同时俘获。并将叠加后的两贝塞尔光束对不同半径的粒子进行微操作,同时采用基于麦克斯韦方程和极化理论的电磁学模型对该过程进行模拟。

| Abstract: | In this paper,we discuss the characteristics of optical trap by using Bessel beam,which means the beam can trap particles simultaneously along the axial of beam in its Zmax.Furthermore,two beams are superposed to manipulate different radii particles,and we simulate this process by electromagnetics model based on Maxwell equation and polarization theory.The results indicate that,firstly,smaller particles can be easily switched at the same situation of two beams' intensity interchanging;secondly,particles can... |
