【 摘 要 】

Propagation theory of elastic wave for ferrite-piezoelectric bilayer structures is presented. The expression for the dispersion relation of the longitudinal mode planar oscillations is derived. It is shown that in limited cases this expression come to dispersion relation for ferrite and piezoelectric accordingly.
