Abstract

This work deals with the simulation study superconducting materials elastic properties. The study is based on the simulation of the acoustic signal V (z) received by the acoustic microscope. The simulated signal enabled us to know the variation of reflection coefficient R(θ ) which behaves as a function of incidence angle θ , from the analysis of R(θ ) and V(z) we determines the elastic constant of the material studied..

Keywords
