摘要：
A sufficient condition for the existence of a trapped wave in a piezoelectric waveguide with a cavity is obtained by reducing the boundary-value problem to the self-adjoint operator in a specially constructed Hilbert space. It differs substantially from a similar condition for a pure elastic waveguide with a defect and, in particular, does not guarantee trapping of a wave by a crack. The examples of the damaged piezoelectric waveguides supporting trapped waves are given.
