共振光学纳米天线表现出不同的长度缩放，由于表面等离子体相比，他们的射频同行。在这封信中，我们解决这个差异，计算波长相关的有效模式折射率n（eff）的圆柱形一维金纳米线波导。我们的研究结果表明，纳米棒光学天线作为色散和有损耗的法布里-Peacuterot谐振器的表面等离子体。
Resonant optical nanoantennas exhibit a different length scaling due to the surface plasmons compared to their radio frequency counterparts. In this letter, we address this difference by calculating the wavelength-dependent effective mode index n(eff) for a cylindrical one-dimensional gold nanowire waveguide. Our results show that nanorod optical antennas act as dispersive and lossy Fabry-Peacuterot resonators for surface plasmons.
