最近表明，完美导体的结构化表面可以支持类表面等离子体模式[Pendry, Science 305, 847 (2004)]。这种结构的厚度至少为波长量级。在这里，使用超过蜡棱镜临界角入射的微波波长辐射，我们量化了厚度远小于入射波长的超材料表面的类表面等离子体色散。
It has recently been shown that the structured surface of a perfect conductor can support surface-plasmon-like modes [Pendry , Science 305, 847 (2004)]. Such structures have a thickness of at least the order of the wavelength. Here, using microwave wavelength radiation incident beyond the critical angle of a wax prism, we quantify the surface-plasmon-like dispersion for a metamaterial surface with a thickness very much smaller than the incident wavelength.
