The time delay of magnetostatic wave in a YIG slab has been studied experimentally, where the nonuniform dc magnetic field is applied normal to a slab surface by using the artificially sharpened magnetic pole piece. The non-dispersive group delay characteristics are found, and the effect of nonuniform magnetic field on the propagation loss is also investigated.
