ALEXANDRIA, Va., Aug. 20 -- United States Patent no. 12,392,932, issued on Aug. 19, was assigned to University of North Texas (Denton, Texas).

"Ultralow emittance metasurface thermal radiation barriers" was invented by Zihao Richard Zhang (Denton, Texas).

According to the abstract* released by the U.S. Patent & Trademark Office: "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 i...
