Metamaterials exhibit properties beyond those exhibited by conventional materials in
conventional scenarios. These have been investigated both theoretically and experimentally …

The coupling of waves between the piezoelectric generators, detectors, and propagating
media is challenging due to mismatch in the acoustic properties. The mismatch leads to the …

Within a time span of 15 years, acoustic metamaterials have emerged from academic
curiosity to become an active field driven by scientific discoveries and diverse application …

As Moore's law approaches its end, two-dimensional (2D) materials are intensely studied for
their potentials as one of the “More than Moore'(MM) devices. However, the ultimate …

Based on the form‐invariance of Maxwell's equations under coordinate transformations,
mathematically smooth deformation of space can be physically equivalent to …

We design and experimentally realize an ultra-broad band metamaterial-based acoustic
absorption material. Unlike traditional acoustic absorbers, the designed device features a …

We design and experimentally demonstrate an acoustic tunnel completely open for
substances like fluids or other energy fluxes to exchange while allowing sound to pass only …

We theoretically design and numerically demonstrate an acoustic one-way metasurface,
which is a planar and acoustically subwavelength layer behaving like a nearly-reflectionless …

Metamaterials are rationally designed periodic micro-or nanostructures that do not exist in
nature. Recently, metamaterials for hydrodynamic phenomena have attracted immense …

We report pseudospin-dependent hybrid topological acoustic metamaterials constructed
from tunable acoustic metamaterials and honeycomb-latticed sonic crystals. Using a …
