摘要：

The dispersion properties of electroacoustic wave modes confined by a superlattice of uniformly moving 180A degrees domain walls in a tetragonal ferroelectric crystal are considered. It is shown that the manifold of partial electroacoustic interfacial waves in the lattice is restricted to the first allowed band, the configuration of which in the plane of spectral variables can significantly vary under the action of the moving domain walls.
