Abstract
In this paper, A new method based on the conservation of momentum theory to calculate the trappping force on microsphere are presented. Using 2-D FDTD algorithm, the distribution of electric and magnetic fields in trapping system is simulated, then the monmentum density distribution and trapping force can be easily getted. Many parameters are taken into accounted involving wavelength of optical source, waist radius, diameter of microsphere and refractive index. The simulation results are in good aggreement with the other experimental observation.
