Abstract
It is shown that when surface magnetostatic waves propagate in a ferrite-metal structure magnetized by a linearly nonuniform field, the phase shift of these waves is many times greater than that accompanying propagation in a ferrite film and also in a ferrite-metal structure magnetized by a uniform field, and may reach extremely high values of tens of thousands of radians. This indicates that ferrite-metal structures magnetized by nonuniform fields are potentially useful for developing microwave shifters.
