The propagation of surface acoustic waves over a solid plate is highly influenced by the\npresence of liquid media on the surface. At the solidâ??liquid interface, a leaky Rayleigh wave radiates\nenergy into the liquid, causing a signification attenuation of the surface acoustic wave amplitude.\nIn this study, we take advantage of this spurious wave mode to predict the characteristics of the\nmedia, including the volume or height. In this study, the surface acoustic waves were generated on\na thick 1018 steel surface via a 5 MHz transducer coupled through an angle beam wedge. A 3Dprinted\ncontainer was inserted on the propagation path. The pulse-echo time-domain responses of\nthe signal were recorded at five different volumes..................
