摘　　要：基于变换热学理论,使用坐标变换方法得到各向异性热导率参数表达式,能同时实现热反射与热连接功能,即热流矢量方向的偏转与位置的移动,利用仿真计算验证了不同方向热流的控制效果。基于等效介质理论,对提出的热学超材料开展了物理实现方案设计,将两种热导率不同的材料,通过交替层叠以及空间取向的选取,达到理论设计效果。最后,探讨了将上述热学超材料结构设计应用于热幻象领域的可行性。Based on the theory of transformation thermodynamics,the anisotropic thermal conductivity parameter expression was obtain by the method of coordinate transformation,which can realize the function of heat reflection and heat connection at the same time,that is,the deflection of the heat flow vector direction and the movement of the position.The control effect of heat flow in different directions was verified by simulation calculation.Based on the equivalent medium theory,the physical realization scheme of the proposed thermal metamaterial was designed.Two materials with different thermal conductivity were alternately stacked and the spatial orientation was selected to achieve the theoretical design effect.Finally,the feasibility of applying the above thermal metamaterial structure design to the field of thermal illusion was discussed.
