我们报道了共振光子隧穿（RPT）通过由金属和电介质交替层组成的一维超材料。经由表面等离子体激元极化子状态的RPT允许具有大波数的倏逝光波被传送通过超材料。这是最近用超级透镜证明的亚波长成像的机制。此外，我们发现随着Al层数量的增加，RPT峰从反射率下降处移动，表明这种移动是由RPT中的损失引起的。(c)2008年美国光学学会。
We report resonant photon tunneling (RPT) through onedimensional metamaterials consisting of alternating layers of metal and dielectric. RPT via a surface plasmon polariton state permits evanescent light waves with large wavenumbers to be conveyed through the metamaterial. This is the mechanism for sub- wavelength imaging recently demonstrated with a super- lens. Furthermore, we find that the RPT peak is shifted from the reflectance dip with increasing the number of Al layers, indicating that the shift is caused by the losses in the RPT.
