Acoustic metamaterials: design, optimization, synthesis, testing

Metamaterials are a novel class of materials possessing some exotic properties, non-existent in nature. Specifically, due to locally resonant behaviour such materials are able to attenuate sound waves in low frequency range, which leads to their potential application as noise insulators.

Project Period: February 2014 – January 2018

The project aims at the geometrical and morphological design of a multi-phase particulate metamaterial for acoustic applications. The point of departure is to understand wave propagation in nonperiodic heterogeneous structures and the assessment of parameters responsible for the control on the width of the band gap. The design of the metamaterial will be based on advanced computational techniques. The ideal metamaterial should be not only efficient in terms of acoustic qualities but also reasonable as for manufacturing process.
