R. Briers et al., A LIQUID WEDGE AS GENERATING TECHNIQUE FOR LAMB AND RAYLEIGH-WAVES, The Journal of the Acoustical Society of America, 102(4), 1997, pp. 2117-2124
A model is developed to describe the excitation of Lamb and Rayleigh w
aves by a Gaussian beam incident on a liquid/air/solid corner. Analyti
cal expressions for the displacement fields of the generated modes are
derived by applying a mode theory that accounts for the contribution
of the reflected waves. Numerical computations illustrate the optimum
conditions under which the strongest stimulation of Lamb and Rayleigh
waves may be expected. (C) 1997 Acoustical Society of America. [S0001-
