It is an old saying that vibration and wave propagation are the same in principle. The saying is applied to vibration of an elastic layer as well as to dispersive Rayleigh wave in the layer. Based on vibration mode analysis for the layer of finite length, the Rayleigh wave characteristics such as dispersion and rotation of particle motion are discussed. Formulation of the impulsive response of the layer leads to familiar relationships between applied force and resulting deflection. The amplitude of the dispersive Rayleigh wave generated by a horizontal and/or vertical impulse is also discussed in reference to Poisson's ratio.
