Modeling a labyrinthine acoustic metamaterial through an inertia-augmented relaxed micromorphic approach
Jendrik Voss, Gianluca Rizzi, Patrizio Neff +1
We present an inertia-augmented relaxed micromorphic model that enriches the relaxed micromorphic model previously introduced by the authors via a term in the…
Analytical model of the acoustic response of nanogranular films adhering on a substrate
Gianluca Rizzi, Giulio Benetti, Claudio Giannetti +2
A 1D mechanical model for nanogranular films, based on a structural interface, is here presented. The analytical dispersion relation for the frequency and lifetimes of the acoustic…
Boundary and interface conditions in the relaxed micromorphic model: exploring finite-size metastructures for elastic wave control
Gianluca Rizzi, Marco Valerio d'Agostino, Patrizio Neff +1
In this paper, we establish well-posed boundary and interface conditions for the relaxed micromorphic model that are able to unveil the scattering response of fully finite-size met…
Exploring metamaterials' structures through the relaxed micromorphic model: switching an acoustic screen into an acoustic absorber
Gianluca Rizzi, Manuel Collet, Félix Demore +3
While the design of always new metamaterials with exotic static and dynamic properties is attracting deep attention in the last decades, little effort is made to explore their inte…
