Abstract
Propagation of magnetostatic waves (MSW) in planar magnetic structures with time-dependent parameters is studied theoretically and experimentally for the case where the structure is based on ferrite films. The time-dependent parameter is chosen to be the magnetizing field, which is taken to be uniform in space and slowly varying in time. Asymptotic perturbation theory is used to obtain an equation for the slowly varying amplitude and a relation for the phase, which describes the time behavior of the frequency and envelope of an MSW pulse. The time behavior of the frequency spectrum of an MSW propagating in an iron-yttrium garnet film is studied experimentally for different forms of modulation of the magnetic field. Space-time focusing of MSW pulses is studied for the case of a time-dependent field.
