Metamaterials (MMs), which include phononic crystals (PCs) as a particular type, exhibit
anomalous wave propagation properties through artificial design of topologies or lattice …

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 …

The pursuit of materials with enhanced functionality has led to the emergence of
metamaterials—artificially engineered materials whose properties are determined by their …

Sustainable energies from weather are the most ubiquitous and non-depleted resources.
However, existing devices exploiting weather-dependent energies are sensitive to weather …

Manipulating elastic waves of all polarizations is highly challenging due to the complex
behavior of elastic waves. To achieve simultaneous broadband vibration attenuation and …

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

Mechanical metamaterials with energy-dissipating properties can provide impact mitigation
in the field of engineering. However, current energy-dissipating metamaterials frequently …

Guided waves, elastic waves propagating through bounded structures, play a pivotal role in
various applications, including ultrasonic non-destructive testing and structural health …

For artificial materials, desired properties often conflict. For example, engineering materials
often achieve high energy dissipation by sacrificing resilience and vice versa, or desired …

In the current exploration, the size-dependent nonlinear dynamical performance of
piezoelectric bridge-type energy harvesters at microscale is analyzed. The proposed …
