The repulsion is to be expected when the two parallel slabs have different electromagnetic properties. By studying different cases containing ordinary materials and metamaterials, we found that the repulsive behavior may possibly appear when the wave impedances, which are used to demonstrate the difference of electric and magnetic properties between two slabs, are smaller and larger than the impedance of vacuum, respectively, and moreover, the greater the difference between two wave impedances, the more easily the repulsive force is obtained.
