1D magneto-plasmonics Periodic Structures

In this article the effect of external DC magnetic eld on dispersion diagram of plasmonic periodic structures will be investigated. In this regard the dispersion diagram for the Voigt and Faraday structures will be derived. Then the effect of bias eld is investigated on the aforementioned structures. Itis seen that tunable periodic structures can be achieved by the magnetoplasmonic con gurations. Different dispersion diagram can be obtained for different modal waves. For both structures there exists transmittance band for frequencies below the plasma frequency. Dispersion diagram and effective permittivity of structures are highly depends on the bias eld. For faraday structures and for the frequency band above the plasma frequency, faraday rotation and polarization conversion can be achieved depends on the operating frequencies, bias eld and dispersion diagram
