Polarization — ( Brit. polarisation) is a property of waves that describes the orientation of their oscillations. For transverse waves, it describes the orientation of the oscillations in the plane perpendicular to the wave s direction of travel. Longitudinal… … Wikipedia
Lamb waves — propagate in solid plates. They are elastic waves whose particle motion lies in the plane defined by the plate normal and the direction of wave propagation. In 1917, the English mathematician Horace Lamb published his classic analysis and… … Wikipedia
