Wave Propagation in One-dimensional Inhomogeneous Structures

Part of the Computational Fluid and Solid Mechanics book series (COMPFLUID)


It is now well-known that the homogeneous plane wave has the form u = Aej(k·xωt), where the wave amplitude A and the wave vector k are real. When A and k become complex numbers, as happens for the linear and dissipative (visco-elastic) system, A decreases with propagating distance and u is called an inhomogeneous wave [24]. Although the inhomogeneous wave is defined in a strict sense for two- or three-dimensional media, the definition can be extended to the one-dimensional situation.
