Abstract : The properties of magnetoelastic surface waves in a variety of propagating structures are presented. The characteristics of magnetostatic surface waves in a thin magnetic plate are discussed including some new features introduced when a conducting layer is on or near the surface of the plate, and when magnetocrystalline anisotropy is taken into account. Convolution and pulse compression signal processing is possible when the new features are employed. Operating principles are discussed. A demonstration of pulse compression by 325 MHz surface waves in CdS layered LiNb03 is discussed and results are presented. (Author)
