Quantum levitation of micromachines made of metamaterials by using Casimir effect

研究发现，如果金的介电函数服从等离子体模型，则金与钇铁石榴石（YIG）板之间的卡西米尔力在接近零频率时具有排斥性。此外，我们还表明，减少YIG板的厚度可以增加排斥力的大小。结合降低平板重量的效果，这可能使薄板在真空中悬浮。此外，我们还发现介电磁性纳米复合材料与超导超材料之间的卡西米尔力也存在排斥性。

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.
