On spurious bulk wave exicitation in SAW grating reflectorson GaAs (001) (110)
Reflection of SAW from groove gratings on cubic crystal is analyzed numerically on the basis of perturbation theory. It is shown that for certain angles of incidence, the conversion of SAW into bulk waves vanishes. This reduces the SAW reflection loss from grating.
