Piezoelectric rods, widely used in physical acoustics as resonators, often work in the high-frequency regime so that the equations of vibrations derived in Chapter 6 become unapplicable in such situations. This Chapter is devoted to the construction of a one-dimensional theory of piezoceramic rods with longitudinal polarization that enables one to determine their resonant vibrations in a wide range of frequencies.
