Journal ArticleDOI
Membrane-Type Acoustic Metamaterial with Negative Dynamic Mass
TL;DR: In this article, the authors present the experimental realization and theoretical understanding of a membrane-type acoustic metamaterial with very simple construct, capable of breaking the mass density law of sound attenuation in the 100-1000 Hz regime by a significant margin.
Journal ArticleDOI
Dark acoustic metamaterials as super absorbers for low-frequency sound
TL;DR: A thin-film acoustic metamaterial, comprising an elastic membrane decorated with asymmetric rigid platelets that aims to totally absorb low-frequency airborne sound at selective resonance frequencies ranging from 100-1,000 Hz, can reach almost unity absorption at frequencies where the relevant sound wavelength in air is three orders of magnitude larger than the membrane thickness.

Journal ArticleDOI
First-principles study of Dirac and Dirac-like cones in phononic and photonic crystals
TL;DR: In this paper, the authors proposed a first-principles theory to study the linear dispersions in phononic and photonic crystals, which is capable of predicting accurately the linear slopes of Dirac and Dirac-like cones at various symmetry points in a Brillouin zone, independent of frequency and lattice structure.
Journal ArticleDOI
Controllable transmission and total reflection through an impedance-matched acoustic metasurface
TL;DR: In this paper, a general design paradigm for a novel type of acoustic metasurface is proposed by introducing periodically repeated supercells on a rigid thin plate, where each supercell contains multiple cut-through slits that are filled with materials possessing different refractive indices but the same impedance as that of the host medium.
