摘要
结合边界元方法,利用离散点表面电流及表面磁流的格林函数得到任意三维几何体及任意材料纳米器件互相作用离散点之间的Casimir力.给出浸泡在液体中纳米器件的"非零点能"Casimir效应,分析Casimir排斥力产生的条件,为实际纳米器件之间Casimir效应分析提供新的数值方法.
A frequency domain electromagnetic algorithm boundary element method is applied for computation of Casimir forces between arbitrary materials with arbitrary geometry. Considering electric and magnetic surface current distributions, Casimir force of two objects in terms of interactions of surface currents is obtained. Casimir effects between dielectric objects embedded in dielectric fluid are presented and numerical conditions of repulsive Casimir force are investigated. Non-zeropoint energy Casimir force calculation method is provided. It can be used for design of realistic MEMS.
