Design and Application of Flexural-Mode WaveguidesFlexural waveguides can be excited either by longitudinal or by flexural vibrations. The former is realized by connecting a longitudinal waveguide perpendicularly to the flexural waveguide. In the latter instance, the driving flexural waveguide is joined endto-end with the driven waveguide.

Torsional-Mode TransducersTorsional-mode transducers represent cylindrical rods of resonance length (normally λ./2). We distinguish two basic techniques for the excitation of torsional vibrations in cylinders:

Rod-Type Torsional-Mode ConcentratorsIn this chapter, a number of relations needed for practical calculations in the design of torsional-mode focusing rods (concentrators) are given on the basis of the solution of the wave equation for the torsional vibrations of an inhomogeneous rod.
