Spatial distribution of the electromagnetic radiation accompanying propagation of magnetostatic surface waves in a ferrite film magnetized by a transversely nonuniform field

A model is proposed for description of the spatial distribution of electrom agnetic waves (EMWs) generated during the propagation of magnetostatic surf ace waves (MSSWs) in a ferrite film (FF) magnetized by a transversely nonun iform field. The EMW radiation pattern calculated using this model has two lobes mutually symmetric relative to the FF plane. The lobes are tilted in the direction of MSSW propagation, the tilt increasing with the MSSW veloci ty approaching the velocity of EMW in the film. The calculated results are in good qualitative agreement with experiment. (C) 2000 MAIK "Nauka/Interpe riodica".
