Abstract
Regions of existence for Stoneley waves are analyzed for the case when isotropic contacting media have different values of Poisson's ratios. The analysis is based on solving the secular equation in Scholte’s form for Stoneley wave velocity. It reveals substantial similarity in shapes of regions of existence at all studied values of Poisson's ratio pairs. A recently observed gap in regions of existence for media with equal Poisson’s ratios is also observed in cases when contacting media have different Poisson’s ratios including both auxetic and non-auxetic media.
