| Abstract | |
We show that a particle emitting in close proximity to a magneto-optical metamaterial substrate can experience a repulsive force if the magnetization is found along the surface plane. An analytical condition for the existence of such a repulsive force is obtained within the near-field approximation. Significantly, the repulsive force can be tuned by varying the filling fraction in a stack of two alternating layers of a metallic magneto-optical material and a dielectric. Potential applications can be envisaged for nanomechanical devices, particularly since similar metamaterial architectures have already been developed experimentally. (AU) | |
