Abstract
The dispersion relation of magnetostatic surface waves (MSSW) propagating in an arbitrary direction in a ferrite slab placed between two metal plates is derived and it is shown as a curved surface in Ω-ξ-ζ space, where Ω is the normalized angular frequency, ξ is the component of the normalized wave number in the direction of dc magnetic field and ζ is the component in the direction perpendicular to dc magnetic field and parallel to the slab surface. The dispersion surface is greatly deformed by changing the normalized spacings A and B between the slab and metal plates. The curve for \xi=0 (a dominant mode) of the Ω-ζ curves which constitute the dispersion surface is free of a cutoff wave number and intersects with Ω axis at specific frequency which is determined by the normalized magnetic field Ω H and A+B , while the other curves for \xi \neq 0 (higher order modes) have a cutoff wave number except in special cases. The cut-off wave number characteristics become curves. A detail discussion is given about asymptotic change of the dispersion surface in the neighborhood of Ω axis.
