In this paper we discuss the effects of multiple scattering to the optical forces on a particle by an evanescent field. We show that the iterative method to process the effects of the interaction between the particle and a plane surface is invalid when the radius of particle is large or when the structural resonance of the particle occurs. By using the generalized minimum residual method to solve the set of equations directly, the divergence appears in the iterative method can be removed completely. As an illustrative example, we discussed the effects of multiple scattering to optical forces on a particle in an evanescent field from an incident plane wave. The interpretations of numerical results are presented in detail.
