Topology optimization of pentamode metamaterials for underwater acoustics
Sebastiano Cominelli, Matteo Pozzi, Francesco Braghin
This study presents an automated topology optimization framework for designing pentamode acoustic metamaterials. It provides precise control over the material effective acoustic pr…
Reduced-weight near-cloaks for underwater invisibility
Davide Enrico Quadrelli, Sebastiano Cominelli, Gabriele Cazzulani +1
Limiting the total weight of an acoustic cloak is of fundamental importance in underwater applications, where buoyancy of the cloaked object is desirable. Unfortunately, it is well…
High Bulk Modulus Pentamodes: the Three-Dimensional Metal Water
Giacomo Brambilla, Sebastiano Cominelli, Marco Verbicaro +2
Despite significant advances in the field of phononic crystals, the development of acoustic metafluids that replicate the behaviour of liquids in three dimensions remains elusive.…
Isospectral open cavities and gratings
Sebastiano Cominelli, Benjamin Vial, Sébastien Guenneau +1
Open cavities are often an essential component in the design of ultra-thin subwavelength metasurfaces and a typical requirement is that cavities have precise, often low frequency,…
