Acoustic metamaterials (AMs), which are materials composed of subwavelength periodic
artificial structures with specific designs, have drawn significant research attention. This is …

Initially proposed to achieve strong noise isolation levels beyond the mass-density law,
acoustic metamaterials (AMMs) have now overturned the conventional views in all aspects …

Vibration control is an overwhelmingly concerned issue that exists in many industrial fields
such as machinery, aerospace and civil engineering. Indeed, in terms of energy perspective …

In this letter, a class of honeycomb acoustic metamaterial possessing lightweight and yet
sound-proof properties is designed, theoretically proven, and then experimentally verified. It …

Over the past decade there has been a great amount of research effort devoted to the topic
of acoustic metamaterials (AMMs). The recent development of AMMs has enlightened the …

In this paper, we investigate a type of anisotropic, acoustic complementary metamaterial
(CMM) and its application in restoring acoustic fields distorted by aberrating layers. The …

We introduce the acoustic equivalent of “supercoupling” by studying the anomalous sound
transmission and uniform energy squeezing through ultranarrow acoustic channels filled …

Zero index materials where sound propagates without phase variation, holds a great
potential for wavefront and dispersion engineering. Recently explored electromagnetic …

In this Letter, we report on the design and experimental characterization of a broadband
acoustic hyperbolic metamaterial. The proposed metamaterial consists of multiple arrays of …

The primary objective of acoustic metamaterial research is to design subwavelength
systems that behave as effective materials with novel acoustical properties. One such …
