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

While embedding acoustic black holes (ABHs) in plates has proved to be a lightweight and
useful solution for noise and vibration reduction, their potential for wave manipulation is only …

The propagation properties of flexural wave in the periodic beam on elastic foundations are
studied theoretically. The wavenumbers and traveling wave characteristics in the beam on …

Recent studies have introduced a new class of two-dimensional acoustic metamaterials
whose dispersion and propagation properties result from the use of geometric …

Circular acoustic black holes (ABHs) on plates help reducing overall vibrations by
concentrating them at the ABH centers, where vibrations get dissipated by means of …

We report on the theoretical and experimental realization of a double-zero-index elastic
waveguide and the corresponding acoustic cloaking and supercoupling effects. The …

We describe an analytical approach that allows calculating the trajectories of an elastic
beam within a two-dimensional phononic crystal-based gradient index medium. The …

In the present Letter, the multiple scattering theory (MST) for calculating the elastic wave
band structure of two-dimensional phononic crystals (PCs) is extended to include the …

Direct numerical simulations of the dynamic response of the phononic crystal to point or
distributed forces via conventional numerical methods are still formidable currently due to …

Fabrication of metallic phononic and photonic crystals of characteristic size between 10 and
1000 μ m remains a challenge in precision using the conventional machining processes or …
