准晶格交错线介质
Interlaced wire medium with quasicrystal lattice
摘要：
提出了一种基于五次旋转对称彭罗斯镶嵌的准晶格交错线介质的设计。研究了这种结构的输运性质。我们区分两个传输制度，即，传播制度有关的低频区间和本地化制度在高频区间。前者在具有平移对称性和不具有平移对称性的结构中都可以观察到，而后者仅限于非周期结构。我们发现，本地化制度是有前途的许多应用，包括工程的有效的多通道设备的电信和成像系统。
英文摘要：
We propose a design of interlaced wire medium with quasicrystalline lattice based on five-fold rotation symmetry Penrose tiling. The transport properties of this structure are studied. We distinguish two transport regimes, namely, propagation regime related to the low-frequency interval and localization regime in the high-frequency interval. While the former is observed in structures both with and without translation symmetry property, the latter is exclusive for aperiodic structures only. We show that the localization regime is promising for many applications including engineering of effective multi-channel devices for telecommunication and imaging systems.
