Thermal emission is typically associated with a blackbody at a temperature above absolute
zero, which exchanges energy with its environment in the form of radiation. Blackbody …

The emission of thermal radiation is a physical process of fundamental and technological
interest. From different approaches, thermal radiation can be regarded as one of the basic …

In recent decades, optical singularities have been extensively investigated with intriguing
phenomena and rich physics, including bound states in the continuum (BICs), exceptional …

From the standpoint of thermal radiation, omnidirectional nonreciprocal thermal radiation
(NTR) is strongly desired for thermal energy harvesting. Here, we propose theoretically …

Blackbody radiation is incoherent and omnidirectional, whereas various novel applications
in renewable energy require a degree of directional control of a thermally emitted beam. So …

Abstract Epsilon-near-zero (ENZ) materials have recently emerged as a promising platform
for infrared nanophotonics. A significant challenge in the design of ENZ-based optics is to …

This paper presents a reconfigurable plasmonic structure consisting of a phase-change
material slab, G e _2 S b _2 S e _4 T e _1 (GSST), overlaid with a fishnet pattern comprising …

The ability to treat the surface of an object with coatings that counteract the change in
radiance resulting from the object's blackbody emission can be very useful for applications …

A novel hybrid plasmonic‐germanium telluride (GeTe) metasurface design, which
demonstrates single‐peak on/off tunability across a spectral range of 2.5–7.5 μm is …

Tailoring of thermal radiation is critical for applications like daytime radiative cooling,
thermophotovoltaic energy conversion, and gas sensing. Phase‐change materials (PCMs) …
