Neural-field design of broadband Rayleigh-wave carpet cloaks under microstructure realisability constraints
David Aznaurov, Davit Piliposyan, Danila Rukhovich +1
Transformation elasticity provides appropriate material distributions for elastodynamic cloaks but the required stiffness tensors generally violate the minor symmetries of Cauchy e…
Stochastic cloaking: concealing a region from diffusive particles
Connor Roberts, Ziluo Zhang, Helder Rojas +4
We introduce "stochastic cloaking," where a region of space is concealed from an ensemble of diffusing particles whose individual trajectories are governed by a stochastic (Langevi…
Robust Quasi-Bound States in the continuum: Accidental and Symmetry-Protected Variants in Dielectric Metasurfaces
Hicham Mangach, Abdelhaq Belkacem, Younes Achaoui +3
Recently, man-made dielectric materials composed of finite-sized dielectric constituents have emerged as a promising platform for quasi-bound states in the continuum (QBICs). These…
Bi-functional metamaterial based on Helmholtz resonators for sound and heat insulation
Brahim Lemkalli, Zine El Abiddine Fellah, Sébastien Guenneau +3
Over the last few decades, both heat and broadband sound reduction have become increasingly significant as a result of concerns about the environment and noise pollution. In order…
Clay metaBrick-based motif to enhance thermal and acoustic insulation
Brahim Lemkalli, Saad Bensallam, Muamer Kadic +4
Acoustic metamaterials have gained popularity as promising materials for enhancing noise reduction. Here, we explore the use of metamaterials, based on Helmholtz resonators (HRs),…
Unveiling Extreme Anisotropy in Elastic Structured Media
Gautier Lefebvre, Tryfon Antonakakis, Younes Achaoui +3
Periodic structures can be engineered to exhibit unique properties observed at symmetry points, such as zero group velocity, Dirac cones and saddle points; identifying these, and t…
