摘　　要：研究金属板和特异材料间的Casimir力。金属板的电磁性质是由实验数据拟合得到,特异材料板的电磁性质则是用Drude-Lorentz模型来描述。通过改变两块材料板的相关参数,研究了Casimir吸引力、排斥力的变化及其相互转化。结果表明,随着两板间距的增加,两板间的Casimir力会经历引力-斥力-引力的转化。The Casimir force between metal and metamaterial slabs is investigated. The magnetodielectric properties of the metal slabs are obtained by fitting experimental data ,and those of the metamaterial slabs are explored with Drude-Lorentz model. It is found that the attractive and repulsive Casimir forces and their mutual transition can be occurred by altering relevant parameters of these two material slabs. The results show that when the separation between these two slabs is increasing ,the Casimir force between two slabs will make a attractive-repulsive-attractive transition.
