Abstract

It is shown that the surface Green function matching method can be readily applied to piezoelectric materials by defining a four-dimensional Green function which includes both the elastic and the electrostatic fields. For an interface system this reduces to one half (with respect to the usual treatments) the order of the secular determinant, with consequent saving in computation. As an illustration an application is made to the study of shear horizontal waves for surfaces and interfaces with 6mm symmetry.
