| 摘 要： | 最近实验证明周期性的光子晶体中存在电磁波的负折射现象，并且观测到亚波长成像．然而，这些研究主要集中在剧期性结构中，对非周期结构的研究还没有相关的报道。文章报道了一种新的理论和实验结果：非周期性十二重准晶光子结构同样存在负折射，并且可以实现超透镜的远场成像。具有这些特性的光子准晶可以广泛的应用于光集成器件中。 |
| 关 键 词： | 准晶 负折射 成像 |

| Abstract: | Recently,negative refraction of electromagnetic waves in photonic crystals was demonstrated experimentally and subwavelength imagingobserved.However,these investigations all focused on the periodic structure.Here we report a new theoretical and experimental finding that negative refraction can occur in certain transparent quasicrystalline photonic structures.More interestingly,a superlens based on 2-dimensional photonic quasicrystals can form a non-near-field subwavelength image whose position varies with the source distance.This property makes such quasicrystals promising for application in a range of optical devices. |
| Keywords: | quasicrystal negative refraction image |
