微机电系统中界面的电磁特性直接决定了它们之间的Casimir力,因此电磁表面的构造就显得尤为重要。理论上,我们利用非单分散的磁性纳米粒子来构建超超材料(MMM)表面,以获得排斥力,该排斥力可以通过外部磁场来调节。根据Lifshitz的理论,我们发现颗粒尺寸分布对Casimir力的影响与颗粒尺寸的期望值有关,当考虑MMM板的电磁参数的各向异性时,Casimir排斥会减小。该研究为利用电磁表面实现Casimir排斥提供了可行的解决方案。
The electromagnetic properties of interfaces in microelectromechanical systems directly determine the Casimir force between them, therefore the construction of the electromagnetic surface is particularly significant. We theoretically utilize non-monodisperse magnetic nanoparticles to construct a meta-metamaterial (MMM) surface to obtain a repulsive force, which can be adjusted by an external magnetic field. According to Lifshitz’s theory, we have discovered that influence of the distribution of particle size on the Casimir force is related to the expectation of particle size, and Casimir repulsion will decrease when taking into account the anisotropy of electromagnetic parameters for MMM plate. This study provides feasible solutions to achieve Casimir repulsion using electromagnetic surfaces.
