Abstract

A study has been performed of a special type of SAWs on piezoelectric substrates that propagate faster than slow quasi transverse bulk waves (QTBW) without leaking into the substrate. Properties of these SAWs resemble, to some extent, those of the SH-polarized Gulyaev-Bleustein wave (GBW) and we refer to them as fast generalized GBW (GGBW). A remarkable specific feature is that fast GGBW can exist on a piezoelectric medium of generic symmetry. They originate because of piezoelectric coupling and can be viewed as the issue of the "localization" of exceptional bulk waves (EBW) that appear in the branch of fast QTBW in the limit of vanishing piezomoduli.
