| 摘要 |
A surface acoustic wave device for use as an amplifier or convolver, or the like, and incorporating a plurality of parallel, spaced rails disposed between and separating a semiconductor slab and a surface acoustic wave propagating planar surface of a piezoelectric substrate a relatively small but finite distance apart, the rails having longitudinal axes aligned with the propagation beam path by and between a pair of spaced electro-acoustic transducers disposed on the substrate.
