The waves that propagate in fluids like water and air are called acoustic waves. Plane waves are the simplest solutions of wave equation as discovered by D'Alembert. In conjunction with Fourier transforms, plane waves are central in the solutions of a variety of problems like waves in layered ...

The characteristic equation for the propagation of elastic waves in a floating ice sheet is derived and discussed, with special emphasis on the evaluation of phase velocity for very large and very small wavelengths. The solutions cannot be reduced to symmetric and antisymmetric modes as in the case...
