Passage of surface magnetostatic waves through magnetic 'valley' and 'ridge'

The propagation of magnetostatic surface waves (MSSWs) in a ferrite film magnetized by a nonuniform magnetic bias field in the shape of a magnetic valley or a magnetic ridge has been investigated theoretically and experimentally. The MSSW beam paths and the beam profiles have been studied at different frequencies for different angles of orientation of the input MSSW transducer relative to the direction of the bias magnetic field. It is noted that the results obtained can aid in the construction of microwave MSSW devices with nonuniform bias fields.<
