The proposed program is inspired by the return of the first edition of the METAGENIERIE2017 school, in which the bases and the fields of application were developed. At the end of the 2017 edition, the expectations of the participants were at the level of practical applications with digital and experimental implementation. It is in this spirit that the METAGENIERIE2019 program will propose five / six experimental / numerical situations based on canonical examples related to fundamental phenomena on acoustic metamaterials. In particular Metagenierie 2019 aims to deepen in more detail several very important aspects of metamaterials from five experimental / numerical situations:
1.- Implementation and characterization of a network of acoustic resonators in the long wavelength regime compared to the characteristic size of the elementary cells. The theory of homogenization will be worked with hyperbolic internal resonance media that will be the subject of practical work.
2.- Implementation and characterization of a network of acoustic resonators in the diffraction regime. In this situation the calculation and plot of the dispersion relations, the study of acoustic propagation properties of metamaterials will be presented.
3.- Implementation and characterization of metamaterials for bending waves (experimental techniques related to the field of application, different frequency regimes).
4.- Implementation and characterization of piezoelectric metamaterials (specific techniques and effects related to piezoelectric materials).
5.- Numerical simulation for metamaterials and phononic crystals. The numerical tools, based on the finite element method, will be introduced for the calculation of the dispersion relations, as well as for calculating the diffusion of a finite medium.
Thus, through these 5 experimental / numerical situations, different fundamental aspects of metamaterials will be highlighted. In particular, around experimental manipulations or numerical simulations, more specialized concepts will be provided.
