Metasurface perfect absorbers for light control: beyond visible/infrared emitters (Invited Paper)
19 August 2024 • 10:55 AM - 11:20 AM PDT | Conv. Ctr. Room 4
Abstract
I will talk about recent progress in perfect absorbers based on plasmonic metasurface and its applications to incandescent light bulbs, narrow/broad-band infrared emitters, and adaptive radiative cooling. In addition, I will discuss all-dielectric perfect absorber using crystalline silicon and its application to all-optical switching based on degenerate critical coupling of electric and magnetic dipoles in Mie resonators.
