Abstract :
Storage of acoustic signals propagating along the surface of a piezoelectric crystal has been shown to be feasible. Previous experiments were performed at 30 MHz on Quartz, with a triode planar gun structure without any focusing electrode. In this paper, a new structure is described which has been designed to meet the requirement for higher-frequency operation (above 100MHz). Experimental results are given and comparison is made with other ways of increasing the capabilities of this storage device.
