MWSW04 - Multiple scattering in engineering and applied sciences

A 3 -dimensional fully natural sonic crystal composed of Aegagropilae, that are spherical aggregates resulting from the decomposition of Posidonia Oceanica, is first analyzed. This fully natural sonic crystal exhibits excellent sound absorbing properties and thus represents a sustainable alternative that could outperform conventional acoustic material. New insight into metaporous surface involving periodically arranged square shaped 2D Helmholtz resonators would then be given. In particular, the closed-form expressions of the effective properties of these 2D-dimensional metaporous materials are derived, including the Willis coupling. Co-authors: L. Barguet, J. Leng, V.
