Solution of the inverse problem of thickness resonances in plates at normal incidence

Obtention of material properties from the measured spectra (magnitude and phase) of the ultrasonic transmission coefficient of a layer of the material measured at normal incidence and over a frequency range that encompases, at least, one order of the thickness resonances.

Two cases are considered:

Homogeneous plate (one layer). Gradient Descent method

IPython notebook (html) example

Shared project on github

Plate made of several layers (layered model). Stochastic Gradient Descent method
