The optical force exerted on a Rayleigh dielectric spherical particle by a photonic jet is investigated in the framework of the Rayleigh approximation. The photonic jet is generated by a plane wave illuminating a Generalized Luneburg Lens (GLLs). The electric field of the photonic jet is calculated using Discrete Dipole Approximation (DDA). The effects of wavelength of incident plane wave, focal length and radius of the GLLs on optical force are analyzed. Numerical results show that the stability of the captured particles can be controlled by changing the incident wavelength, focal length and radius of the GLLs.

光子射流产生的瑞利粒子上的光力

在瑞利近似的框架中研究了光子射流对瑞利介电球形颗粒施加的光学力。光子射流由平面波照射广义伦堡透镜 (GLL) 产生。使用离散偶极近似 (DDA) 计算光子射流的电场。分析了入射平面波波长、GLL 焦距和半径对光力的影响。数值结果表明，捕获粒子的稳定性可以通过改变 GLL 的入射波长、焦距和半径来控制。
