Surface acoustic wave existence in anisotropic media. A review

Abstract

A short review of studies on the problem of the existence of the surface acoustic waves in anizotropic solids is presented. There is given the derived expression of surface impedance tensor first introduced by Ingebrigsten and Tonning. The method proposed by Barnett and Lothes for determining whether a subsonic surface wave could propagate on a given cut of a given anisotropic solid in a given direction is discussed.
