Phononic crystals (PCs) and metamaterials (MMs) can exhibit abnormal properties, even far
beyond those found in nature, through artificial design of the topology or ordered structure of …

In solid state physics, a bandgap (BG) refers to a range of energies where no electronic
states can exist. This concept was extended to classical waves, spawning the entire fields of …

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

This paper investigates a technique for broadband vibration suppression using a graded
metamaterial beam. A series of local resonators with the same mass but different natural …

Mechanical metamaterials exhibit some superior mechanical properties such as ultrahigh
strength-to-weight ratio, negative bulk-modulus, negative stiffness, negative mass-density …

Metamaterials and phononic crystals (PCs) with artificially designed periodic microstructures
have attracted increasing research interests due to their unique properties that cannot be …

By employing periodic electrical boundary conditions, an innovative method to generate
actively tunable topologically protected interface mode in a “homogeneous” piezoelectric …

Achieving vibration and/or wave attenuation with locally resonant metamaterials has
attracted a great deal of attention due to their frequency dependent negative effective mass …

DOI: 10.1002/adma. 201604009 of tunable digital elastic metamaterial, where the internal
resonators within each unit cell can be switched by controlling the current of electromagnets …

As the counterpart of electromagnetic and acoustic metamaterials, elastic metamaterials are
artificial periodic elastic composite materials offering the possibility to manipulate elastic …
