利用具有交流克尔效应的各向异性材料和非线性材料的组合，可以调谐椭球与平板之间的卡西米尔力。采用基于麦克斯韦应力张量的时域有限差分法（FDTD）进行了数值计算。结果表明，通过改变激光的强度和位置以及材料的性质，可以显著地改变作用力。不同材料性质的椭球和板结构之间的敏感变化为光学器件集成到纳米机电系统（NEMS）中提供了新的可能性。
The Casimir force between an ellipsoid and a plate can be tuned by using the combination of anisotropic materials and nonlinear materials exhibiting the AC Kerr effect. The force was obtained numerically by using the FDTD method, based on the Maxwell's stress tensor. The results indicate that the force can be significantly varied by changing the intensity and location of the laser, as well as the properties of material. The sensitive changing between ellipsoid and plate structure with different materials' properties provides new possibilities of integrating optical devices into nano-electro- mechanical systems (NEMS).
