摘要

我们提出了太赫兹波在等离子体结构中的空间定位(安德森定位)的第一个实验演示。这种效应是通过在一维等离子体晶格中加入无序而产生的。我们讨论了无序对波导传播特性的影响，在停止带之外的新模式的出现，以及它们的输运特性。我们还测量了局域模式的空间特性，并将局域化长度与其他实验演示进行了比较。研究结果与先前发表的理论著作一致。

Anderson localization in terahertz plasmonic waveguides

We present the first experimental demonstration of spatial localization (Anderson localization) of terahertz waves in plasmonic structures. The effect is brought upon by inclusion of disorder in a one dimensional plasmonic lattice. We discuss the effect of disorder on the propagation properties of the waveguide, the appearance of new modes beyond the stop band, and their transport properties. We also measure the spatial properties of the localized mode and compare the localization length to other experimental demonstrations. The results are consistent with prior published theoretical works.
