FIG. 1.

Infinite medium; shear beam patterns for three different frequencies all sharing the same phase speed of . (a), (b), (c) radial components of the displacement (d), (e), (f) z-component of the displacement at , , and respectively. Note that only a cubic portion of the medium near the axis of symmetry is shown; The medium extends in all directions to infinity.
