    "abstract": "By using a method, previously established to calculate electromagnetic\nfields, we compute the force of light upon a metallic particle. This procedure\nis based on both Maxwell\u0027s Stress Tensor and the Couple Dipole Method. With\nthese tools, we study the force when the particle is over a flat dielectric\nsurface. The multiple interaction of light between the particle and the surface\nis fully taken into account. The wave illuminating the particle is either\nevanescent or propagating depending an whether or not total internal reflection\ntakes place. We analyze the behaviour of this force on either a small or a\nlarge particle in terms of the wavelength. A remarkable result obtained for\nevanescent field illumination, is that the force on a small silver particle can\nbe either attractive or repulsive depending on the wavelength. This behaviour\nalso varies as the particle becomes larger.",
