Influence of conductive and viscous liquid on the properties of the Bleustein-Gulyaev wave in potassium niobate crystal

Anomalous resisto-acoustic effect is a fundamental property for weakly inhomogeneous acoustic waves. Due to this effect the velocity of such waves initially increases, achieves the maximum and only then decreases with increasing conductance of a layer or media placed at the surface of piezoelectric half-space. Earlier it has been shown that this effect exists for aforementioned waves propagating in contact with conductive liquid. In this paper we investigate the influence of conductive liquid viscosity on this effect.
