In this paper, we presented a case study of guided wave propagation in a plate with one side immersed in water. With the acquisition of time–space wavefield and application of 2D FT, the frequency–wavenumber spectrum is obtained in which the wave modes and the dispersion relation can be discernibly viewed. The analysis also manifests the presence of guided wave modes as well as the quasi-Scholte wave mode in the one-sidedly immersed plate. Below 300 kHz, the quasi-Scholte mode dominates.
