In order to explore the relationship restoring Casimir force between the doped silicon slab and electromagnetic metamaterials with related parameters,basing on the generalization of the Lifshitz theory and Green function for Maxwell force tensor,the Casimir force between the doped silicon slab and metamaterials were calculated.The results show that the magnitude and the direction of the Casimir force can be tunable by varying the doping level,the thickness of doped silicon slab,and filling factor of metamaterials.Consequently,the force can be controlled by those factors.
