A Disordered Photonic Medium Enabling Ultrabroadband Light Scattering and Selective Longwave Infrared Emission
Zhenpeng Li, Mathis Degeorges, Nithin Jo Varghese +1
A surface that selectively emits heat in the long-wave infrared (LWIR) can enable passive cooling in hot environments while retaining partial radiative insulation in cold condition…

Radiative Cooling and Thermoregulation of Vertical Facades with Micropatterned Directional Emitters
Mathis Degeorges, Jyothis Anand, Nithin Jo Varghese +1
We demonstrate a micropatterned directional emitter (μDE) with an ultrabroadband, azimuthally selective and tailorable emittance across the thermal wavelengths and over wide angle…
