Abstract

We analytically investigate the forces due to Surface Plasmon Polariton (SPP) modes between finite and infinitely thick metal slabs separated by an air gap. Using the Drude model and experimentally determined values of the dielectric functions of gold and silver, we study how frequency dispersion and loss in the metals affects the behavior of the SPP modes and the forces generated by them. We calculate the force using the Maxwell Stress Tensor for both the attractive and repulsive modes.

摘要

我们通过分析研究了由空气间隙隔开的有限厚度和无限厚度金属板之间表面等离激元极化激元（SPP）模式所产生的力。利用德鲁德模型以及通过实验测定的金和银的介电函数值，我们研究了金属中的频率色散和损耗如何影响SPP模式的行为以及它们所产生的力。我们使用麦克斯韦应力张量计算了吸引模式和排斥模式下的力。
