摘要：

In terms of spherical vector wave functions (SVWFs) utilizing integral localized approximation method, the incident field and scattering field expansion coefficients can be derived. Using Generalized Lorenz Mie Theory (GLMT), the radiation force (RF) exerted on a single spherical particle by a LG beam is calculated. The effects of OAM states, beam waist, particle size, dielectric constants of particle and surrounding medium of axial RF have been numerically analyzed in detail.
