Abstract
We develop a method to study the optical and magneto-optical response of perforated metallic films with magneto-optic media embedded within their holes. Due to the strong electromagnetic field confinement associated with the excitation of the transmission resonances appearing in this type of structures and nonreciprocal nature of the magneto-optical phenomena, strongly enhanced conversion of the polarization state in both reflected (magneto-optical Kerr effect) and transmitted (magneto-optical Faraday effect) waves was found. Possibility to reach huge rotation angles is demonstrated by increasing magneto-optic holes filler/background optical contrast, which appears to be responsible for the resonance quality.
