Theoretical models for MM integration in aeroacoustics

Report of the general theory for the aeroacoustic integration of metamaterial, and the computed properties for transmission in bulk metamaterials associated to all the basic material concepts analysed (e.g., anisotropic, periodic/layered, poro-elastic, fractal,…). Restriction to idealized 2D problems (metasurfaces) for the modelling of surface treatments, such as liners or coatings.
