00925njm 22002777a 4500 dc Smith, Thomas Benjamin author Torre, Iacopo author Principi, Alessandro author 2019-04-24 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 characterized by different Hall conductivities but identical normal conductivities. A single bound mode is found, which can localize 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.
