摘要：

Trans verse acoustic waves that occur at the boundary Of two Piezoelectric halfspaces separated by a viscoclastic liquid layer are studied theoretically. Three variants of layered structures with different numbers of metallized interfaces are considered. It is demonstrated that two types of waves exist in each of these structures. The waves are localized near the boundaries and differ in both their structure and the dependences of the complex wave numbers on the frequency or the gap width. The properties of this family of shear horizontal waves are described. (C) 2001 MAIK "Nauka/Interperiodica".
