| Research Abstract |
We found that the Casimir force between a gold plate and a Yttrium Iron Garnet (YIG) plate, which is magneticldielectric material can repulsive, if the dielectric function of gold obeys plasma model near zero frequency. Furthermore, we showed that the magnitude of the repulsive force can be increased by decreasing the thickness of the YIG plate. Combined with the effect of decreasing the weight of the plate, this might enable a thin plate to levitate in vacuum. Additionally, we found that the Casimir force between dielectricmagnetic nanocomposite and superconductive metamaterial can also be repulsive.
