title: Investigation of extraordinary optical transmission and Faraday effect in one-dimensional metallic-magnetic gratings.
abstract: We have investigated extraordinary optical transmission (EOT) with enhanced Faraday effect in one-dimensional metallic-magnetic slit arrays under polar magnetization using the rigorous coupled-wave analysis performed by the Airy-like internal reflection series. The roles of surface plasmon polaritons and quasi-guided waves are studied in which the latter plays a key role. Based on the mechanism of EOT with an enhanced Faraday effect, both enhanced transmittance and enhanced Faraday effect are optimized by adjusting the geometric parameters of slit arrays evaluated by the figure of merit.
