Edge modes and Fabry-Perot Plasmonic Resonances in anomalous-Hall Thin Films
arXiv:1812.08798 · doi:10.1103/PhysRevB.99.155422
Abstract
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.
arXiv comment11 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
