Passive daytime radiative cooling represents one of the boldest answers to tackle the future
cooling needs of the built environment and to mitigate urban heat island effects. Recent …

Efficient absorption of solar radiation is desired for the renewable energy sector, such as
solar thermophotovoltaics and solar thermal applications. In order to minimize thermal re …

Efficient light sources compatible to complementary metal oxide semiconductor (CMOS)
technology are key components for low-cost, compact mid-infrared gas sensing systems. In …

In this work, we numerically investigate the radiative properties of metamaterial
nanostructures made of two-dimensional tungsten gratings on a thin dielectric spacer and …

The goal of this paper is to introduce a local form of Kirchhoff law to model light emission by
nonequilibrium bodies. While absorption by a finite-size body is usually described using the …

Incandescent filaments and membranes are often used as infrared sources despite their low
efficiency, broad angular emission, and lack of spectral selectivity. Here, we introduce a …

Thermophotovoltaic (TPV) devices can convert thermal radiation directly into electricity. To
improve the efficiency of TPV systems, wavelength-selective emitters are designed to take …

Thermal emission caused by the thermal motion of the charged particles is commonly
broadband, un-polarized, and incoherent, like a melting pot of electromagnetic waves, which …

Both wavelength selectivity and directional insensitivity are highly desired in
thermophotovoltaic applications. A concept of a magnetic-polariton-enhanced …

Kirchhoff's law plays a vital role in radiation heat transfer, which has been recently
generalized to hold for both reciprocal and nonreciprocal materials. However, the …
