Annotation
Using the geometro-acoustic approach, it is shown that antisymmetric acoustic oscillations can propagate along the apex of a solid wedge whose local thickness varies quadratically with the height. These oscillations are concentrated near the apex, their phase velocities are characterized by nonmonotonic frequency dependence and can be made arbitrarily small as the wedge truncation height tends to zero.
