Abstract :
The paper discusses some basic achievements in theoretical studies on SAW propagation in anisotropic solids. In particular, the following issues are reviewed: existence theorems for subsonic surface and interface waves, leaky SAWs and their relation to "supersonic" SAWs and fast exceptional bulk waves, the resonance reflection of bulk waves in the vicinity of leaky wave branches. General conclusions are exemplified by numerical findings.
