The magneto-optical (MO) responses of layered Epsilon-Near-Zero (ENZ) metamaterials are investigated.
Two structures, a free standing ENZ-MO slab, and a multi-layer structure containing an ENZ-MO layer are considered.
The transmittances of circular polarizations for the slab are obtained analytically and investigated numerically.
The transmittances and Faraday rotation of the multilayer structure are studied numerically.
The obtained results demonstrate the circular polarization filtering effects for both structures.
