Ultra-broadband illusion acoustics for space and time camouflages [PDF]
Nature CommunicationsInvisibility cloaks that can suppress wave scattering by objects have attracted a tremendous amount of interest in the past two decades. In comparison to prior methods that were severely limited by narrow bandwidths, here we present a practical strategy ...

Parity Metamaterials and Dynamic Acoustic Mimicry [PDF]
ResearchWhile parity transformation represents a fundamental symmetry operation in physics, its implications remain underexplored in metamaterial science. Here, we introduce a framework leveraging parity transformation to construct parity-inverted counterparts ...

Acoustic Tamm states of three-dimensional solid-fluid phononic crystals
The Journal of the Acoustical Society of America, 2018 In this work, the existence and propagation of acoustic Tamm states at the interface of air and a face-centered cubic solid-fluid phononic crystal composed of spherical air voids interconnected by cylindrical air channels are demonstrated. Supercell band structure computations via the finite element method reveal surface bands for Tamm states on (100),

Acoustical properties of double porosity granular materials [PDF]
, 2011 Granular materials have been conventionally used for acoustic treatment due to their sound absorptive and sound insulating properties. An emerging field is the study of the acoustical properties of multiscale porous materials.

Broadband low-frequency sound absorption in open tunnels with deep sub-wavelength Mie resonators
Frontiers in Physics, 2022 We report both experimentally and numerically that near-perfect absorption of low-frequency sound is realized in an open tunnel embedded with two deep sub-wavelength (0.085 λ) Mie resonators. The resonators are composed of a multiple-cavity structure and

Analytical investigation of nonreciprocal response in 1D nonlinear photonic crystals
Scientific Reports, 2017 The nonreciprocal response of the SHG process in 1D periodical nonlinear photonic crystals with a defect embedded has been theoretically studied by solving the nonlinear coupled equations. The nonreciprocal response has been deduced analytically with the
