采用表面模式技术，对由面内光轴各向异性介质隔开的两个平行板的Casimir力进行了解析和数值计算。结果表明，各向异性对Casimir力的相对影响随着分离的进行而减小，不同的各向异性符号对应于对Casimir力方向的不同影响。各向异性可以改变介电介质的介电常数平均值，进而改变介电常数与介电介质之间的不等性，这是对上述行为的物理解释。对热效应进行了计算，并与前人的计算结果进行了比较。结果表明，在我们的情况下，非零温度在小间隔时倾向于抑制各向异性的影响，而在大间隔时则增强各向异性的影响。
The Casimir force is calculated both analytically and numerically by the surface mode technique in the configuration of two parallel plates separated by an anisotropic media with in-plane optical axis. The result reveals that the relative impact of the anisotropy on the Casimir force decreases with the separation and different signs of the anisotropy could correspond to different impacts on the directions of the Casimir force. The anisotropy can change the average value of permittivity of the intervening media and then change the inequality among the permittivities of the two plates and the intervening media, which is the physical explanation for the behaviours above. The thermal effect is also calculated and compared with previous results. It shows that the non-zero temperature tends to suppress the impact of anisotropy at small separations but to enhance it at large separations in our case.
