BACKGROUND Metasurfaces have opened up a number of remarkable new approaches to
manipulate light. These flat optical elements are constructed from a dense array of strongly …

With rapid advances in optoelectronics, electrochromic materials and devices have received
tremendous attentions from both industry and academia for their strong potentials in …

Radiative cooling materials spontaneously radiate long-wave infrared (LWIR) to the cold
outer space, providing cooling power that is preferred in hot seasons. Radiative cooling has …

The sun (∼ 6,000 K) and outer space (∼ 3 K) are two significant renewable thermodynamic
resources for human beings on Earth. The solar thermal conversion by photothermal (PT) …

Phase-change materials (PCMs) provide a unique combination of properties. On
transformation from the amorphous to crystalline state, their optical properties change …

Since the first demonstration, remarkable progress has been made in the theoretical
analysis, structural design, numerical simulation, and potential applications of metamaterial …

Metasurfaces have become a rapidly growing field of research in recent years due to their
exceptional abilities in light manipulation and versatility in ultrathin optical applications. They …

We review the basic physics and applications of a special class of planar metamaterials,
often called metasurfaces, which are composed of optically thin and densely packed planar …

The study of ideal absorbers, which can efficiently absorb light over a broad range of
wavelengths, is of fundamental importance, as well as critical for many applications from …

A dual-tunable metamaterial absorption modulator is proposed based on a hybrid vanadium
dioxide-graphene configuration. When vanadium dioxide is in the state of metal, the design …
