Abstract
AbstractThis chapter offers a comprehensive exploration into the realm of thermal metamaterials, emphasizing their transformative potential in regulating the three primary modes of heat transfer: conduction, convection, and radiation. The foundation of this exploration is rooted in the theory of transformation omnithermotics, which has been instrumental in unifying these heat transfer modes. The article delves into various functional designs, including omnithermal metamaterials capable of thermal cloaking, concentration, and rotation. The effective medium theory further broadens the scope, allowing for the simultaneous manipulation of the three heat transfer modes. A notable highlight is the introduction of omnithermal restructurable metasurfaces, which exhibit dual properties in both infrared and visible light spectrums. Additionally, this chapter touches upon other artificially designed structures, such as radiative cooling and engineered cellular solids, drawing parallels with natural counterparts like wood and bone. The BCC lattice structure, in particular, is spotlighted for its unique thermal and mechanical properties, making it a promising candidate for future applications. The culmination of these findings underscores the vast potential of thermal metamaterials in diverse applications, from energy efficiency to aerospace engineering.
