N2 - Optical trapping is of great practical importance in various fields such as physics, biology and nanofluidics or microfluidics. In order to trap and move particles efficiently, it is necessary to theoretically study the radiation pressure face (RPF) exerted on the particles firstly. The RPF exerted on a sphere induced by laser-sheet beam is analyzed using Debye series expansion (DSE). The DSE can isolate the contribution of each scattering process to RPF, and give a physical explanation of RPF. The DSE is employed to the simulation of RPF corresponding to different scattering processes (diffraction, reflection, refraction, etc.) in detail, and gives the physical mechanism of RPF. The effects of various parameters such as scattering mode p and beam position to RPF is researched.
