Abstract
A monolithic dielectric coating composed of microscale periodic high-contrast gratings on multilayers of high and low refractive index optical materials is described, which is deposited on metal thin-films of flexible polymer insulation sheeting. The emittance can be minimized to any blackbody temperature, using parameter optimization of high-contrast grating phase-shift mode conditions. The high-low refractive index infrared-transparent multilayer is based on Fabry-Pérot cavity, but with non-quarter-wave thicknesses to achieve multilayer insulation conductance below that of metal films. This ultralow emittance coating is most relevant to thermal management of refrigeration and electronic components.
