摘要：

A two-component thin-layer acoustic superlattice (one-dimensional phononic crystal), in which one of the layers of the superlattice period is near the proper ferroelastic phase transition, is considered. The necessary conditions under which a bulk elastic wave incident on the outer surface of the superlattice excites a refracted wave with negative acoustic refraction (at the fundamental or multiple frequency) have been determined.
