Abstract We propose a theoretical concept of a far-field radiative thermal rectification device that uses a phase change material to achieve a high degree of asymmetry in radiative heat transfer. The proposed device has a multilayer structure on one side and a blackbody on other side. The multilayer structure consists of transparent thin film of KBr sandwiched between a thin film of V... https://www.nacrack.com/mega-pick-Legacy-Kelly-Green-Spear-Cool-Fit-Adjustable-Visor-White-quick-deal/
