摘要

提出了一种光学陷阱的数学模型，其中纳米粒子被介电表面的光子射流反射形成的驻波场捕获。建立了纳米粒子在介质（液体）中存在粘性摩擦时阱场作用下的运动方程。对纳米粒子在阱中稳定捕获的条件进行了分析估计。通过数值求解运动方程，分析了摩擦对捕集器稳定性的影响。

Dynamics of a Nanoparticle in an Optical Trap Formed by a Photonic Jet Modulated by a Standing Wave in a Microfluidic Channel

A mathematical model has been proposed for an optical trap, in which a nanoparticle is captured by the field of a standing wave formed upon reflection of a photon jet from a dielectric surface. The equations of motion for the nanoparticle under the action of a trap field in the presence of viscous friction in the medium (liquid) have been formulated. The conditions for stable capture of a nanoparticle in the trap have been estimated analytically. The role of friction in the stability of the trap has been analyzed by numerically solving the equations of motion.
