含单负特异材料阵列结构的透射特性

Transmission Properties of Arrayed Structures Containing Single Negative Metamaterials

利用共振隧穿机制,对三层结构阵列的透射特性进行了研究。在特定条件下,由一层单负特异材料和两层介质组成的三层结构可实现隧穿。为了进一步改善透射性质,将三层结构作为基本单元,与空气层排列成周期型阵列结构。研究结果表明,三层结构在周期型阵列结构中所占比例对透射率有很大的影响,并且发现周期型阵列结构与三层结构相比透射率显著提高。

We study the transmission properties of the tri-layer structures which consist of single negative metamaterials, and two layers of dielectric by the resonant tunneling mechanism. Tri-layer structures can realize resonant tunneling under certain condition. In order to improve transmission properties of tri-layer structures, we base on it designed the new arrayed structures, whose tri-layer structures with air layer arranged in cycle type array structures. The result show that the different ratio of tri-layer structures in arrayed structure can affect the transmittance of tri-layer structures, and the transmittance of array structures also higher than single tri-layer structures.
