报告摘要:Thermal metamaterials have attracted attention for their ability to control heat transfer. The key challenge is to achieve precise control of thermal transport in complex systems. To tackle this, transformation thermotics is used as a core framework. By applying geometric transformations, we developed innovative thermal metamaterials, including 3D thermal cloaks, topological corner states, and so on. These designs enable directional heat transfer, intelligent temperature control, and energy-efficient non-reciprocity. Experimental results validate these designs, demonstrating practical viability. The findings show that thermal metamaterials enhance control over heat processes, with potential applications in infrared protection and intelligent heat management. The integration of machine learning into metamaterial design offers further optimization opportunities. In conclusion, this talk introduces thermal metamaterials' theoretical understanding and opens new paths for real-world applications. Future research will focus on expanding topological thermotics and intelligent design frameworks for advanced thermal control.
