On Accounting for the Microrotation of Particles of an Elastic Medium According to Cosserat’s Simplified Theory During Electroelastic Wave Propagation in a 6 mm Class Piezoelectric Crystal

On Accounting for the Microrotation of Particles of an Elastic Medium According to Cosserat’s... Abstract The article reveals how the micro polarity of a material influences the propagation of a one-dimensional electroelastic wave along different sections of a 6mm class piezoelectric crystal. It is shown that micro polarity leads to dispersion of a one-dimensional electroelastic wave and prohibits the propagation of high-frequency elastic shear waves. In the case of a normally incident electromagnetic wave on the surface of a piezoelectric half-space along the direction of the polarization axis of the piezoelectric crystal, three branches of electroelastic waves localized near the surface appear in the half-space. The frequency range of the existence of these waves is found from the dispersion equation. The behavior of the wave characteristics and frequency zones is numerically studied as a function of the micro polarity of the piezoelectric crystal. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Acoustical Physics Springer Journals

Abstract

Abstract The article reveals how the micro polarity of a material influences the propagation of a one-dimensional electroelastic wave along different sections of a 6mm class piezoelectric crystal. It is shown that micro polarity leads to dispersion of a one-dimensional electroelastic wave and prohibits the propagation of high-frequency elastic shear waves. In the case of a normally incident electromagnetic wave on the surface of a piezoelectric half-space along the direction of the polarization axis of the piezoelectric crystal, three branches of electroelastic waves localized near the surface appear in the half-space. The frequency range of the existence of these waves is found from the dispersion equation. The behavior of the wave characteristics and frequency zones is numerically studied as a function of the micro polarity of the piezoelectric crystal.
