RESUMO
We report on the numerical study to model a lensless optical manipulation trap to investigate some observed features as guiding and modulation effects caused by a micro-sphere. For this we calculate the field distribution and force exerted upon a micrometer-sized spherical dielectric particle in an evanescent field. The method of calculation is based on the integral equation formalism describe by A. A. Maradudin, et. al., and A. Mendoza-Suárez and E. R. Méndez. The numerical experiments were done considering a two-dimensional model.
