Flow of the Energy of a Surface Spin Wave in a Tangentially Magnetized Ferrite Plate
摘要
Abstract
A theory describing the propagation of electromagnetic waves in a tangentially magnetized bi-gyrotropic layer is used to calculate for the first time dependences of the orientation of the energy flow on the orientation of the wave vector for an arbitrary surface-surface spin wave (whose distribution over the layer’s thickness is described by two different wave numbers) in a ferrite plate, a special case of a bi-gyrotropic layer.
