The introduction of engineered resonance phenomena on surfaces has opened a new
frontier in surface science and technology. Pillared phononic crystals, metamaterials, and …

The study of phononic materials and structures is an emerging discipline that lies at the
crossroads of vibration and acoustics engineering and condensed matter physics. Broadly …

Despite their engineering significance, locally resonant metamaterials are facing the
challenge to cope with the need for broad-range band gap adjustment at low-frequencies …

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

We investigate elastic periodic structures characterized by topologically nontrivial bandgaps
supporting backscattering suppressed edge waves. These edge waves are topologically …

An innovative special class of magnetorheological metamaterial is proposed to achieve a
tunable band gap using a new frequency feedback control law. By using the frequency …

Linear acoustic metamaterials (LAMs) are widely used to manipulate sound; however, it is
challenging to obtain bandgaps with a generalized width (ratio of the bandgap width to its …

In this study, we investigate high-performance piezoelectric energy harvesting at multiband
frequencies. Previous harvesting platforms were limited to a high-frequency range and …

Locally resonant metamaterials are characterized by bandgaps at wavelengths that are
much larger than the lattice size, enabling low-frequency vibration attenuation. Typically …

This paper is concerned with flexural wave propagation and vibration transmission in beams
with periodically attached vibration absorbers. Such periodic systems feature unique wave …
