研究了负折射率材料对产生Casimir排斥效应的影响.两材料板间的Casimir排斥力的发生取决于两板以及其间媒质的电磁特性,通过理论与数值结果的分析研究给出电磁特性所影响排斥力的产生趋势.对于由Drude-Lorentz型色散关系描述等效介电常数和磁导率的负折射率材料,调节各特征频率参数可实现Casimir排斥效应.
The effect of negative refractive index materials on Casimir’s repulsive effect is studied.The Casimir repulsion between two plates depends on the electromagnetic properties of the two plates and the media between them.The theoretical and numerical results show that the influence of electromagnetic properties For the negative refractive index material with Drude-Lorentz type dispersion relationship describing equivalent dielectric constant and permeability, Casimir repulsion effect can be achieved by adjusting the characteristic frequency parameters.
