Abstract: Guided elastic waves are propagated in a waveguide, including a central core region and an outer cladding region. The bulk shear elastic wave velocity in the cladding region is larger than in the core region. The thickness of the cladding region is sufficient so that the particle displacement profile falls nearly to zero before reaching the outer surface of the cladding region. The waveguide is mounted in any suitable medium for protecting it against external mechanical shock and for providing any necessary mechanical support therefor. Different guide configurations and both torsional mode and radial mode transducers are shown.
