摘要：

The mode conversion of a bulk wave into a Stoneley wave at the downward step of a thin layer partially covering a solid substrate is studied. An analytical expression for the amplitude of the excited Stoneley wave is derived by applying mode theory. The excitation amplitude has two pronounced maxima: at grazing and at Rayleigh angle incidence of the bulk wave. The latter maximum is almost independent of the material characteristics of the thin layer. (C) 1997 Acoustical Society of America. [S0001-4966(97)06209-7] PACS numbers: 43.35.Pt [HEB].
