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.…
