Abstract
Passive electromagnetic cooling is achieved using a first enclosed chamber having an antenna array surface, and a second chamber comprising open space external to the first enclosed chamber, wherein the open space comprises the sky. An interface is defined between the first chamber and the second chamber, wherein the antenna array surface is positioned with respect to the first chamber to thermally insulate between the interior of the first chamber and the open space of the second chamber. The antenna array surface is configured to direct beams from the interior of the first chamber towards the zenith of the sky. Solar irradiation in the optical spectrum range is reflected in the pyramidal dielectric surfaces or the ground plane in the dielectric rod array antenna.
