Abstract :
The letter describes theoretical results of the effects of surface metallisation on surface-skimming-bulk-wave (SSBW) and Bleustein-Gulyaev-wave (BGW) propagation characteristics for rotated Y-cuts of quartz. For a range of rotations, the surface metallisation increases the surface mechanical displacement of the BGW relative to the SSBW. The metallisation is ineffective in trapping the SSBW energy close to the surface.
