Magnetostatic surface wave propagation on a periodic YIG film layer
1979
The filter characteristics of a magnetostatic surface wave propagating in a layered YIG film corrugated on one layer and noncorrugated on the other are described. The effect of the saturation magnetization of a noncorrugated layer on the filter is analytically evaluated by solving the exact dispersion relation. Also, the magnetic loss effect on the filter is considered. It is found that the Q value of the filter in our new model is generally twice as large as that of contemporary periodic YIG film filters.
