复杂非均匀手征介质粒子系对矢量涡旋波束的散射作用是当前国际研究热点,其解析解理论一直是具有挑战性的研究课题。本项目基于势函数理论和角谱展开技术,研究高拓扑荷、紧聚焦矢量涡旋波束的光场描述,以及强度、振幅、相位、偏振和轨道角动量分布特性。运用广义米理论和多重散射方程,研究聚集非均匀分层手征介质球/柱与分层手征介质椭球等模型对不同拓扑荷矢量涡旋波束的散射解析解,分析螺旋相位、手征参数、波束与粒子相对空间取向的影响;着重研究手征介质粒子的自旋和轨道角动量特性以及矢量涡旋波束与聚集非均匀手征粒子系的相互作用,建立散射模型、分析波束的手征参量对散射特征、辐射力、扭矩和结合力等影响规律,揭示相关的物理机理,阐明涡旋光势阱中聚集非均匀手征粒子系的俘获、牵引、结合、轨道和自旋转运动等动力学特征,丰富迁移波束类型,研究成果为人工手征超材料自排列、生物粒子诊断、光镊与微操控等领域提供理论支撑。
英文摘要
The study on scattering of complex non-uniform chiral particle systems by vector vortex beams is always the hotspot of international research, and its analytical solution has been a challenging research topic. Based on the potential function theory and angular spectrum expansion technology, this project is to study the optical field description of the tightly focused vector vortex beams, as well as the distribution characteristics of intensity, amplitude, phase, polarization and orbital angular momentum. Using the generalized Lorenz-Mie theory and Multiple Scattering equations, the analytical solutions to the scattering of vector vortex beam by models such as clustered non-uniform chiral layered spheres / columns and chiral layered ellipsoids are studied. The effects of spiral phase, chiral parameters and relative spatial orientation of beams and particles on the scattered field are analyzed. Focused on studying the spin and orbit angular momentum characteristics of chiral media and the interaction of vector vortex beams with clustered non-uniform chiral particle systems. We develop the scattering model and work on the influence of chiral parameters on scattering characteristics, trapping force, radiation torque and optical binding force as well as the physical mechanism, and clarify the dynamic characteristics of capture, traction, combination, orbit and spin motion of the non-uniform chiral particle system in the vortex potential well, and enrich the types of redirected beams. The theory will provide theoretical support for research fields of artificial chiral metamaterials self-alignment, biological particles diagnosis, optical trapping and micromanipulation.
