Abstract
We investigate the possibility of optical trapping by evanescent photons localized near a subwavelength aperture. The radiation force exerted on a dielectric sphere near the aperture is numerically analyzed, and the result shows that the force on the sphere is attractive to the aperture. It is also found that the magnitude of the radiation force is larger than those of two other forces, the gravity and the force due to thermal fluctuation in water.
