Propagation of acoustoelectric waves in a hollow cylinder whose physicomechanical properties have a radial symmetry axis

Abstract

The general case of off-axis propagation of acoustoelectric waves in hollow cylinders made of a piezoelectric material such as a crystal of the class mm2 orthorhombic system with a two-fold radial symmetry axis is investigated. The basic system of equations for the wave problem in circular cylindrical coordinates is reduced to eight equations of the Hamiltonian type in the radial coordinate. A solution of the generalized spectral problem for harmonic waves is found by numerical methods. Special cases of the general problem are considered. The results of solving specific problems are analyzed.
