Study of the lamb waves propagation along a plate in contact with a randomly inhomogeneous heterogeneous medium

Abstract

Ultrasonic surface waves have been widely applied in the practice of control over characteristics of technological media. The reason for this is the following features of ultrasonic waves. The first feature is the relatively large concentration of energy in a wave due to the small magnitude of the layer of its location. The second feature is the possibility for obtaining an ultrasonic signal from any point of the surface (including curvilinear), along which it propagates.
