Abstract :
An acoustic-surface-wave beam, launched along the chord of a disc, will fold compactly into an extended delay path. The rounded edges of the disc act as geodesic lenses. Beam-guiding can be obtained by repetitive focusing at the edge. A 96 ¿s 41 MHz prototype disc delay line is described.
