Resumen
A surface acoustic wave can interact with dislocations that are close to the surface. We characterize this
interaction and its manifestations as scattered surface acoustic waves for different orientations with
respect to the surface of an edge dislocation. For dislocations that are parallel or perpendicular to the free
surface, we present an analytical result for short dislocations with respect to the wave-length that reproduce
qualitatively the main features observed for dislocations of various sizes.
