Infrared (IR) adaptation phenomena are ubiquitous in nature and biological systems. Taking
inspiration from natural creatures, researchers have devoted extensive efforts for developing …

Thermal emission is a ubiquitous and fundamental process by which all objects at non-zero
temperatures radiate electromagnetic energy. This process is often assumed to be …

The discovery, design and development of materials are critically linked to advances in
many areas of research, and optics is no exception. Recently, the spectral region in which …

The reciprocity between thermal emission and absorption in materials that satisfy the
Lorentz reciprocity places a fundamental constraint on photonic energy conversion and …

Inspired by the developments in photonic metamaterials, the concept of thermal
metamaterials has promised new avenues for manipulating the flow of heat. In photonics …

Controlling the directionality of emitted far-field thermal radiation is a fundamental challenge.
Photonic strategies enable angular selectivity of thermal emission over narrow bandwidths …

With its unique and exclusive linear and nonlinear optical characteristics, epsilon-near-zero
(ENZ) photonics has drawn a tremendous amount of attention in the recent decade in the …

The engineering of the spatial and temporal properties of both the electric permittivity and
the refractive index of materials is at the core of photonics. When vanishing to zero, those …

Regarded as a promising alternative to spatially shaping matter, time-varying media can be
seized to control and manipulate wave phenomena, including thermal radiation. Here …

Spinning thermal radiation is a unique phenomenon observed in condensed astronomical
objects, including the Wolf-Rayet star EZ-CMa and the red degenerate star G99-47, due to …
