Abstract

Passive radiative cooling has garnered significant attention in recent years due to its potential in addressing the energy consumption of conventional cooling systems. Plasmonic and metamaterial structures have been found to be effective broadband absorbers due to their selective emissive spectra, thin thickness, design flexibility, and the ability to excite plasmonic or photonic resonances. This study explores the use of bowtie shape plasmonic metamaterials for the development of novel, structurally simple radiative cooling devices. We show that by designing and optimizing a periodic high index-low index alternating layers (SiO2-TiO2), broadband reflection in visible and near-infrared spectrums is achievable. While to achieve broadband absorption in the transparency window (8-13 um), metamaterial is utilized.
