Scattering of forward bulk magnetostatic waves by a defect of the surface of a ferromagnetic film magnetized at an arbitrary angle

Abstract

The solution for the diffraction problem of scattering of magnetostatic waves by an arbitrary shal low defect situated under the surface of a ferromagnetic film magnetized at an arbitrary angle is obtained in the quasi static approximation. Expressions for the energy flux density of scattered magnetostatic waves in the far field zone are found. The results of computations of the time averaged flux density of bulk magneto static waves reflected from rectangular and circular shallow irregularities are presented.
