Abstract : This patent describes a surface acoustic wave device having a thin magnetostrictive film deposited on the surface between its input and output transducers. A variable D.C. field is applied to the film to vary its characteristics and thereby correspondingly continuously vary the delay or phase shift of the surface acoustic wave. (Author)
