Abstract
Rayleigh to compressional wave conversion has been described by Toda and Murata [1] for plane waves and by Farnell et. al. [2] for radial waves. The phenomena results in compressional plane waves in a fluid, which propagate away from the solid surface containing the Rayleigh waves at an angle equal to the inverse cosine of the ratio of the velocity in fluid to the velocity on the surface. With cylindrically symmetrical Rayleigh waves, the compressional waves in the fluid form a solid hollow cone. The convergence of these waves forms a line of focus in the fluid, the extent of which is determined by the radius of existence of the Rayleigh waves on the solid interface. This result has unique applications in acoustic microscopy [3,4].
