Acoustic metamaterials gave birth to the engineering counterpart of amazing cutting-edge novelties from physics, which discovered and proved unusual ways for steering pressure waves. Outcomes such as superlensing and invisibility cloaking are the most famous and impressive applications.
However, the practical realization of these applications remains a significant challenge. Our research group is dedicated to advancing this frontier by focusing on the design and production of a 3D acoustic cloak aiming to potentially render submarines invisible to sonar detection.
Following a complete investigation of analytical and numerical models, the candidate will also acquire hands-on experience with advanced manufacturing techniques, including additive manufacturing (stereolithography) and investment casting. The project will culminate in an experimental campaign conducted in the newly established NARWAL acoustic laboratory at the Lecco campus, aimed at validating the acoustic performance of the fabricated cloak. In the process, the candidate will also gain a strong foundation in metamaterial theory and underwater acoustics.
