Hybrid state of Fabry–Perot and Tamm plasmon-polariton modes in structures with different plasmon layers

The paper presents the investigation of magnetophotonic crystals with different metal layers for the formation of a Tamm plasmon polariton. It was revealed that the structure with the Ag layer has the resonance with a higher optical  quality factor. It is shown how a change in the symmetry of the structure affects the properties of the hybrid state of Fabry–Perot and Tamm plasmon polariton modes. The effect of oblique incidence and polarization of incident light  on the localization of light in the layers of the structure is demonstrated.
