摘要
我们研究等离激元在部分涂覆反常霍尔材料薄膜的金属二维表面上的传播。由此形成的三个区域由两条锐界面分隔,其特征为不同的霍尔电导率但相同的法向电导率。我们发现一个单一的束缚模,其可局域于任一界面,并在该区域上具有不对称的势分布。对于传播模,我们计算了穿过磁区域的反射与透射系数。我们发现作为等离激元入射角函数的艾里透射图样,具有尖锐的极大与极小值。因此该系统表现为一个高品质滤波器。

11 pages, 7 figures. Upon revision, the basic content and analysis of the paper is unchanged but the emphasis on topological insulators has been removed. The title and abstract has been changed to reflect this. Damping of the bound mode has been included
