• Acoustic waves are analysed that are guided by the intersection of the surface and the interface of two elastic quarter-spaces. The domain of existence of these one-dimensionally guided waves in the material parameter space is determined for Poisson media. It is found that this domain is entirely contained within the existence domain of Stoneley waves and is much smaller than the latter.

The domain of existence of these one-dimensionally guided waves in the material parameter space is determined for Poisson media. It is found that this domain is entirely contained within the existence domain of Stoneley waves and is much smaller than the latter. The new class of guided acoustic waves may be regarded as a combination of two Rayleigh surface waves with additional localization at the interface between the two media, or they may be interpreted as perturbed edge waves.…
