Abstract

The interaction of the light carrying orbital angular momentum (OAM) with a single spherical particle is explored using a commercial multi-physics simulation platform. The scattering of light with wavelength of 0.532 µm from an ice particle is presented. The research focuses on studying the light-matter interface within an observation volume of radius 10 times the wavelength (5.32 µm) and present near-field magnitude and phase of the scattered field. We place the particle at the various locations of a Gaussian beam, as well as move it to through the vortex and annulus of the light that carries OAM with topological charges of 1, 2 and 3. The numerical solutions showcase the variations of the scattering field complex values and provide a valuable insight in the field behaviour near and inside the particle for different illumination. We show two and three-dimensional scattering field magnitude and phase spatial distributions and their correlations.

携带轨道角动量的激光束从粒子散射:近场强度和相位数值研究
利用商用多物理场仿真平台探讨了携带轨道角动量(OAM)的光与单个球形粒子的相互作用。研究介绍了波长为 0.532 µm 的光从冰颗粒上散射的情况。研究重点是研究半径为波长(5.32 微米)10 倍的观测体积内的光-物质界面,以及散射场的近场幅度和相位。我们将粒子放置在高斯光束的不同位置,并使其穿过带有拓扑电荷为 1、2 和 3 的 OAM 的光涡旋和环面。数值解展示了散射场复值的变化,并为了解不同光照下粒子附近和内部的场行为提供了宝贵的见解。我们展示了二维和三维散射场幅度和相位空间分布及其相关性。
