The Scattering of a Cylindrical Shear-Axial Wave by a Circular Cavity in Piezoelectric Crystal ()
ABSTRACT
The features of a cylindrical shear-axial wave scattering by a
circular cavity in piezoelectric crystal of 6(4)-class of symmetry are
discussed. It is shown that the basic integral characteristics of scattering—scattering
indicatrix and total cross-section scattering have large changes with approach
of a linear shear-axial wave source to cavity boundary. The small-scale
oscillations in spectra of scattering are caused by the interference
contribution of waves circulating on a boundary as they are capable of effective capture
by concave metallized boundary of a cavity.
