All programs are written in Python 2.7 / 3.5
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
Plate made of several layers (layered model). Stochastic Gradient Descent method
Module for the desing and optimization of piezoelectric transducers
Pyton implemented Gradient Descent algorithms for Inverse Problems solution.
