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 …

In the last two decades, seismic metamaterials have attracted significant attention of
researchers because of the characteristic of the bandgap which can be used to control …

In the past decades, many mechanical metamaterials with uncommon static properties have
been reported. On the other hand, mechanical metamaterials possessing extraordinary …

The advancement in electromagnetic metamaterials, which commenced three decades ago,
experienced a rapid transformation into acoustic and elastic systems in the forms of …

Inertial amplification has been utilized in phononic media as a mechanism for the generation
of large band gaps at low subwavelength frequencies. A unique feature in an inertial …

The aim of this study is to design a two-dimensional solid structure with embedded inertial
amplification mechanisms that shows an ultrawide stop band (band gap) at low frequencies …

Realizing a low-frequency and broad bandgap is extremely challenging because the lattice
constant, equivalent stiffness, and equivalent density must be taken into account in practice …

In this work, new beam and plate metamaterials with interconnected local resonators are
proposed. This design promotes the splitting and coupling between transverse and …

This paper presents a new class of locally resonant (LR) metamaterials with quasi-zero
stiffness (QZS) in three dimensions. The monolithic QZS property is achieved by optimizing …
