Numerical analysis of dispersion relations of normal waves in a cylindrical piezoelectric waveguide
Source abstract
Abstract
A dispersion equation for symmetric normal waves in a piezoelectric hollow cylinder with axial polarization is derived. Numerical calculations are performed for a piezocylinder made of barium titanate piezoceramic at two relative thicknesses of a cylinder wall. The total spectra of normal waves—namely, real, imaginary, and complex modes—are presented. Quasi-longitudinal, quasi-transverse, and quasi-electric waves for which both acoustic and electric magnitudes are nonzero are considered.
