Negative Nonconservative Forces: Optical “Tractor Beams” for Arbitrary Objects

S. Sukhov and A. Dogariu

Based on the conservation of linear momentum on scattering from arbitrary objects, we demonstrate the generation of nonconservative optical forces that act in a direction opposite to the propagation of the incident beam. The concept can be applied to tailor the force fields produced on nonabsorbing bodies regardless of their sizes and shapes.
