中文摘要: 近年来, 人工周期性电磁材料的新颖物理性质已获得了广泛的关注,其中超材料(metamaterial)和光子晶体这两种人工电磁材料,以其对电磁波传输的精确控制能力,引起了人们极大的兴趣。本申请将分析两者在某些物理特性上的内在联系及潜在应用价值。我们将研究并对比超材料与介电质光子晶体的相移特征,建立两者在相移上的相互等效关系,得到由介电质光子晶体等效低损耗超材料的高效途径。进一步研究由超材料构造的光子晶体的相移特性,探讨超材料的引入对光子晶体的透射、反射相移性质的影响,从相移角度上探讨光子带隙内的隧穿透射模的形成机制。还将研究含超材料光子晶体中表面等离激元(SPP)的激发条件和传输特性,探讨各界面SPP之间的相互耦合作用,结合光子晶体的能带结构,实现对电性和磁性SPP的选择性激发和传输控制。通过本申请项目的研究,可望拓展光子晶体和超材料的应用前景,为微光电子器件的研制和开发提供新的方向。

英文摘要: Recently, artificial periodic electromagnetic (EM) materials have attracted much interest due to their novel physical properties. Most of the attentions has focused on two kinds of artifical EM materials, metamaterials and photonic crystals, because they can precisely control the transmission of EM waves. This project will discuss the relation of some physical properties of the two artificial materials. We will investigate and compare the properties of the phase shift of the metamaterials and dielectric photonic crystals, and will try to establish their equivalent mechanism based on their properties of phase shifts, and then we may find an efficient way to realize low-loss metamaterials by dielectric photonic crystals. We will also investigate the properties of the phase shift of photonic crystals composed of metamaterials. When the metamaterials are introduced to the photonic structures, the influence to the properties of transmission phase shift and reflection phase shift of the photonic crystals will be discussed. We will try to present the physical mechanism of the appearence of tunneling modes inside the photonic band gap from the phase shift point of view. We will also investigate the exciting conditions and transmission properteis of the surface plasmon polariton (SPP) in the photonic crystals containing
