Tunable magneto-optical Faraday and polar Kerr rotations in a plasma-ferrite metamaterial.

Magneto-optical (MO) metamaterials are a new degree of freedom in the modern technologies due to their pivotal role in paving way for appealing applications. In this paper, a new type of metamaterial composed of plasma and ferrite layers is proposed, and based on the matrix method and numerical calculations is characterized. It is identified that plasma-ferrite metamaterial (PFMM) exhibits a significant MO response with large polarization rotation angles and ellipticities in both reflection and transmission geometries.
