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…
Adjoint Sensitivities for the Optimization of Nonlinear Structural Dynamics via Spectral Submanifolds
Matteo Pozzi, Jacopo Marconi, Shobhit Jain +2
This work presents an optimization framework for tailoring the nonlinear dynamic response of lightly damped mechanical systems using Spectral Submanifold (SSM) reduction. We derive…
Enhanced Sensitivity and Wave-Structure Interaction in Nonsingular Flat-Band Lattices with Compact Localized States
Emanuele Riva, Jacopo Marconi, Francesco Braghin
This paper investigates the dynamics of compact localized modes in one-dimensional flat-band elastic lattices. Flat dispersion arises from destructive interference between neighbor…
Creating compact localized modes for robust sound transport via singular flat band engineering
Riva Emanuele, Federico Bellinzoni, Francesco Braghin
We experimentally demonstrate the emergence of flat-band-induced compact-localized modes in acoustic Kagome lattices. Compact localized states populate singular dispersion bands ch…
Optimal Design of Broadband, Low-Directivity Graded Index Acoustic Lenses for Underwater Applications
Sebastiano Cominelli, Francesco Braghin
Manipulating underwater pressure waves is crucial for marine exploration, as electromagnetic signals are strongly absorbed in water. However, the multi-path phenomenon complicates…
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.…
