| 摘 要： | 利用谐振腔模型,研究了单负超材料构造的多层结构中的表面态的物理机制。发现当满足谐振条件时,在多层结构中将产生表面态,该谐振条件取决于谐振腔内的相位变化。基于上述理论,以单负超材料构造的6层结构为例,分析了该结构的表面态的产生条件和分布情况。该研究为设计含奇特电磁局域特性和隧穿特性的超材料设备提供了有效的途径。

| Abstract: | The physical mechanism of the surface states in multilayered structures consisting of single-negative metamaterials was investigated by using a simple resonant cavity model. It is indicated that the surface states and their corresponding tunneling transmission modes appear when the resonant condition is satisfied. Such resonant condition depends on the phase changes inside the resonant cavity. Taking a six-layered single-negative structure based on the resonant cavity model as an example, the generation and distribution of the surface states were investigated. The study offers an effective method for designing metamaterial devices with novel electromagnetic localizing and tunneling properties. |
