Calculated transmission properties of Au/YIG waveguide with different Au thicknesses.
(a) Au thickness dependence of wavelength. Red bold line λ1 and blue dot line λ2 correspond to the wavelengths of modes k1 and k2 denoted in Fig. 2b. Open squares show the wavelengths obtained by the FEM calculation in Fig. 3. Green broken lines λFS, λPEC show that of the free slab and the slab metallized by a perfect electric conductor. (b) Au thickness dependence of attenuation length. Red bold line Latt 1 and blue dot line Latt 2 correspond to modes k1 and k2. Open circles are the results of the FEM calculation with error bars from the exponential curve fitting of the magnetization decay.
