Bottom Line: The magnetostatic surface waves (MSSW) propagation in a layered structure composed of ferrite film covered by air and on top of metamaterial (MTM) placed on metal is discussed.Dispersion equations which relate the parameters of different layers are derived and used to analyse propagation of MSSW.It is found that the MSSW excitation band depends on the thickness of the MTM layer and ferrite layer.

ABSTRACT
The magnetostatic surface waves (MSSW) propagation in a layered structure composed of ferrite film covered by air and on top of metamaterial (MTM) placed on metal is discussed. Dispersion equations which relate the parameters of different layers are derived and used to analyse propagation of MSSW. It is found that the MSSW excitation band depends on the thickness of the MTM layer and ferrite layer.

Fig6: The normalized frequency as a function ofky in the limitw → ∞ atγ = 0.1 for different values ofsas indicated in the figure. a) real part and b) imaginary part.

Mentions: Figure 6 exhibits the relation between ω/ωp and ky at the limit w → ∞ at γ = 0.1, and s varies as follows: s1 = 6.2 μm, s2 = 7.2 μm, s3 = 8.2 μm and s4 = 9.2 μm. It is shown that MSSW propagates in both directions ± y. However, it propagates in one or the other direction at certain ranges of frequencies. It also changes as s changes.Figure 6
