Phononic crystals (PnCs) control the transport of sound and heat similar to the control of
electric currents by semiconductors and metals or light by photonic crystals. Basic and …

We are witnessing an unprecedented expansion of Internet of Things (IoT) market, whose
nodes are already outnumbering human population several times. Despite the huge …

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

Thermal transport at the nanoscale level is attracting attention not only because of its
physically interesting features such as the peculiar behavior of phonons due to their …

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

Right after the first edition was published in 2007, I was invited to give seminars at a number
of universities in several countries. At that time, many people considered nanotechnology …

Thermal metamaterials have amazing properties in heat transfer beyond naturally occurring
materials owing to their well-designed artificial structures. The idea of thermal metamaterial …

Unlike classical heat diffusion at macroscale, nanoscale heat conduction can occur without
energy dissipation because phonons can ballistically travel in straight lines for hundreds of …

The world communicates to our senses of vision, hearing, and touch in the language of
waves, because light, sound, and even heat essentially consist of microscopic vibrations of …

Phononic crystals and acoustic metamaterials are periodic structures whose effective
properties can be tailored at will to achieve extreme control on wave propagation. Their …
