Abstract
Sagittally polarized, mixed polarized, and leaky interface acoustic wa ves at a 180 degrees ferroelectric domain boundary in tetragonal bariu m titanate are numerically studied. The peculiarities of slowness surf ace of bulk waves in barium titanate are discussed. Extraordinary leak y modes with unusual field structure and reverse power flow at the dep th are described.
