金属薄膜间Casimir力热修正的低频特性

The Low-Frequency Character of the Thermal Correction to the Casimir Force between Metallic Films

J. R. Torgerson, S. K. Lamoreaux

摘要:

Casimir力的有限温度修正的频谱可以通过使用有限传导率金属板的Lifshitz形式来确定。我们表明,TE电磁模式的校正是由频率如此之低,板不能被建模为理想的电磁波。我们还解决了有关的问题,在金属导体的表面和内的电磁场的行为,并claculate使用适当的低频金属边界条件的表面模式。我们的结果带来的tehrmal修正到协议与先前获得的实验结果。

英文摘要:

The frequency spectrum of the finite temperature correction to the Casimir force can be determined by the use of the Lifshitz formalism for metallic plates of finite conductivity. We show that the correction for the TE electromagnetic modes is dominated by frequencies so low that the plates cannot be modelled as ideal dielectrics. We also address the issues relating to the behavior of electromagnetic fields at the surfaces an within metallic conductors, and claculate the surface modes using appropriate low-frequency metallic boundary conditions. Our result brings the tehrmal correction into agreement with experimental results that were previously obtained.
