Abstract: In the paper the influence
of the nanocomposite polymeric layer on value of radiation losses accompanying
the propagation of antisymmetric Lamb wave in piezoelectric plate bordering
with liquid is investigated. It is shown that the using of matching layer leads
to the increasing of effectiveness of bulk wave radiation into liquid at the
propagation of A0 wave. The optimization of the acoustical
characteristics of matching layer and the geometry of the structure is carried
out. The obtained theoretical data are confirmed by the experimental results.
The presented structures can be useful for the development of the waveguide
