Polarization and angle quasi-independent metamaterial crystal with electromagnetically induced transparency based on plasmon hybridization.

We theoretically investigate the optical transmission properties of a specific type of plasmonic metamaterial crystal layer that exhibits polarization and angle independence inside a band of electromagnetically induced transparency (EIT). The hybridization of the plasmons associated with two interleaved arrays of nanorings of different radii leads to destructive interference between their respective plasmon transmission modes. Both plasmon resonances produce bright modes associated with electric dipole oscillation. The EIT is produced by destructive interference between emitted fields of these modes. The presented metamaterial crystal offers new insights into designing optical metamaterials with wide field of view, quasi-omnidirectional polarization, and quasi-isotropic transmission.
