Inversion of acoustic material signature of layered solids

The simplex inversion technique is applied to the acoustic material signature (AMS) of layered solids to obtain thickness and material properties of layers. It is shown in this paper that by careful application of the simplex technique, it is possible to extract much information about a multilayered specimen from its AMS. A brief review of different inversion techniques is also given in the paper from which the relative advantages of using the simplex alogrithm over other techniques are derived.
