The leaky Rayleigh wave and Scholte wave at the interface between water and porous sea ice

Abstract

This paper extends the study on reflection and refraction of waves at the interface of water and porous sea ice by Yew and Weng [J. Acoust. Soc. Am. 82, 342–353 (1987)]. The behavior of leaky Rayleigh waves and Scholte waves generated by a line cylindrical wave source at a distance below the interface is analyzed. It is demonstrated that a wave receiver in the water would pick up a direct wave from the source, a specularly reflected wave from the interface, a leaky Rayleigh wave, and, if the source and receiver are close to the interface and to each other, a Scholte wave. The effects of porosity and frequency on the behavior of these surface and interface waves are also studied. PACS numbers: 43.30.Ma
