Edge modes and Fabry-Perot plasmonic resonances in anomalous-Hall thin films Smith, Thomas Benjamin Torre, Iacopo Principi, Alessandro Plasmon propagation Metallic two-dimensional surface Anomalous-Hall material Hall conductivity Bound mode Asymmetric potential profile Reflection and transmission coefficients Airy transmission patterns High-quality filter. 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.
