    Hello, I'm an expert in the field of acoustics and materials science. Let's delve into the concept of Rayleigh waves. Rayleigh waves are a type of surface acoustic wave that travel along the surface of solids. These waves are characterized by a particle motion that is retrograde and elliptical, meaning the particles move in a direction opposite to the wave's propagation. They are named after Lord Rayleigh, the British scientist who first described them in the 19th century. Rayleigh waves are particularly significant in the field of non-destructive testing (NDT). In NDT, these waves are used to detect flaws and defects in materials without causing any damage to the material itself. The way these waves interact with discontinuities in the material can reveal the presence of defects. They can be generated in various ways, including by a localized impact, such as a hammer strike, or through piezo-electric transduction, where an electric field is used to create mechanical stress in a piezo-electric material, which in turn generates the wave. read more >>
