Photonic metamaterials are man-made structures composed of tailored micro-or
nanostructured metallodielectric subwavelength building blocks. This deceptively simple yet …

Solar energy is abundant and environmentally friendly. Light trap** in solar-energy-
harvesting devices or structures is of critical importance. This article reviews light trap** …

Metamaterials have been deployed for a wide range of fields including invisible cloak,
superlens, electromagnetic wave absorption and magnetic resonance imaging, owing to …

Titanium nitride (TiN) has emerged as one of the most promising refractory materials for
plasmonic and photonic applications at high temperatures due to its prominent optical …

The Purcell effect explains the modification of the spontaneous decay rate of quantum
emitters in a resonant cavity. For quantum emitters such as chiral molecules, however, the …

We experimentally demonstrate a low-loss multilayered metamaterial exhibiting a double-
negative refractive index in the visible spectral range. To this end, we exploit a second-order …

Metamaterials, artificially structured materials consisted of sub-wavelength unit cells, have
attracted tremendous attentions in physics, material science, and engineering over the past …

Giant chiroptical responses routinely occur in three dimensional chiral metamaterials (MMs),
but their resonance elements with complex subwavelength chiral shapes are challenging to …

Phase-change materials (PCMs) have great potential in applications for data storage, optical
switching and tunable photonic devices. However, heating the whole of the phase change …

The magnetic response of most natural materials, characterized by magnetic permeability, is
generally weak. Particularly, in the optical range, the weakness of magnetic effects is directly …
