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 …

Radiative cooling is the process by which an object on the Earth's surface loses heat by
emitting thermal radiation into space through the atmospheric window. Because thermal …

Photoelectric conversion (PC) is an essential process for the devices based on the utilization
of electrical signals, such as solar cells, sensors, imaging, and communication. As an …

Vanadium dioxide (VO2) based metamaterial perfect absorbers (MPAs) have high potential
application values in sensing gas molecules. However, a tuning mechanism via temperature …

Conventional metasurfaces cannot adjust the electromagnetic responses once the
structures are determined. In this paper, we numerically demonstrate a thermally switchable …

Inspired by the growing family of Van der Waals materials, hBN supported phonon
polaritons have attracted much attention due to their inherent hyperbolic dispersion …

Broadband optical absorbers are significant for applications in solar energy harvesting,
thermal emitters, and infrared detection. Broadband solar absorbers should have the …

The demand for miniature, low-cost, utmost efficient optical absorbers triggered ongoing
research efforts to minimize the overall design thickness, particularly the photo-active layer …

Breaking the traditional Abbe diffraction limit to realize super-resolution is attractive for many
applications. In past decades, based on the concept of optical superoscillation, different …

The broad spectrum near unity solar absorber shows important significance in the solar
energy conversion. In this work, a polarization independent broadband and wide-angle …
