霍尔薄膜中的边缘模和法布里-珀罗等离子体共振

Edge modes and Fabry-Perot Plasmonic Resonances in anomalous-Hall Thin Films

Thomas Benjamin Smith, Iacopo Torre, Alessandro Principi

摘要:

本文研究了金属二维表面局部涂敷霍尔材料薄膜时等离子体激元的传播。由此产生的三个区域,由两个尖锐的界面分开,其特征在于不同的霍尔电导率,但相同的正常电导率。一个单一的绑定模式被发现,它可以本地化的任何接口,并有一个不对称的电位分布在整个区域。对于传播模式,我们计算了通过磁性区域的反射和透射系数。我们发现Airy传输模式与尖锐的最大值和最小值作为等离子体激元入射角的函数。因此,该系统表现为高质量的过滤器。

英文摘要:

We study plasmon propagation on a metallic two-dimensional surface partially coated with a thin film of anomalous-Hall material. The resulting three regions, separated by two sharp interfaces, are characterised by different Hall conductivities but identical normal conductivities. A single bound mode is found, which can localise to either interface and has an asymmetric potential profile across the region. For propagating modes, we calculate the reflection and transmission coefficients through the magnetic region. We find Airy transmission patterns with sharp maxima and minima as a function of the plasmon incidence angle. The system therefore behaves as a high-quality filter.
