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 …

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 …

Negative refraction of elastic waves has been studied and experimentally demonstrated in
three-and two-dimensional phononic crystals, but Bragg scattering is impractical for low …

Phononic crystals have been proposed about two decades ago and some important
characteristics such as acoustic band structure and negative refraction have stimulated …

We present the first experimental demonstration of focusing ultrasound waves through a flat
acoustic metamaterial lens composed of a planar network of subwavelength Helmholtz …

Nanoscale spacecrafts have shed light on an audacious but promising vision for interstellar
travel to neighboring planets beyond the solar system. The nanocrafts can be accelerated to …

Advances in low power design open the possibility to harvest ambient energies to power
directly the electronics or recharge a secondary battery. The key parameter of an energy …

Acoustics is a classical field of study that has witnessed tremendous developments over the
past 25 years. Driven by the novel acoustic effects underpinned by phononic crystals with …

This paper presents a comprehensive review of the literature and trends on the design of
