  • Acoustic metamaterial for isolation and method for the production thereof
    Patent number: 10978037
    Abstract: A porous acoustic bead resonator is provided, wherein the Young's modulus of the material of the resonator is lower than 1 GPa and the porosity of the resonator is comprised between 20% and 50%, most of the pores of the resonator being filled with a gas and most of the pores being interconnected, via at least one pore, with the exterior of the resonator.
    Type: Grant

  • Method of imaging using topologic energy calculation
    Patent number: 7654142
    Abstract: The method for obtaining an image of a part to be inspected includes the steps of determining, by simulation, the ultrasonic field (s0) generated by the propagation of a wave in a flawless reference part; transmitting an ultrasonic wave toward the part to be inspected; measuring the field (um) returned by the part to be inspected; subtracting from the field (um) returned by the part to be inspected an ultrasonic field (u0) obtained from a previous corresponding measurement on the reference part; calculating a variable related to the topological energy (ET) in the reference part on the basis of the field (s0) determined by simulation and of the field (um?u0) obtained by subtraction; and determining the image of the part to be inspected on the basis of the values for this variable.

  • Imaging method based on calculation of topological energy
    Publication number: 20070215823
    Abstract: The method for obtaining an image of a part (10) to be inspected includes the steps consisting in determining, by simulation, the ultrasonic field (s0) generated by the propagation of a wave in a flawless reference part (9); transmitting an ultrasonic wave toward the part to be inspected; measuring the field (um) returned by the part (10) to be inspected; subtracting from the field (um) returned by the part to be inspected an ultrasonic field (u0) obtained from a previous corresponding measurement on the reference part (9); calculating a variable related to the topological energy (ET) in the reference part (9) on the basis of the field (s0) determined by simulation and of the field (um?u0) obtained by subtraction; and determining the image of the part (10) to be inspected on the basis of the values assumed by this variable.
