摘　　要：针对通过变换热力学理论设计的热超材料难以制备的问题,将细观力学的中性夹杂思想引入对热流传递路径的控制中,设计出圆柱形热幻像器件,并讨论了幻觉材料的导热系数与半径之间的关系。数值仿真和实验结果表明:通过在原始目标A外涂覆一层设计的幻觉材料,就可以使得探测器从外部探测出幻像目标B的热特征,从而达到很好的干扰作用。该研究为利用热超材料实现目标隐身提供了一种新的可行方法,同时也大大降低了材料的制备难度。Aiming at the difficulty of preparation for thermal metamaterial,the idea of inclusion in the micro-mechanics was introduced into the control of the heat flow path,thus the cylindrical thermal illusion device was designed successfully.The relationship between the radius of the illusion material and the thermal conductivity was discussed,so that it could flexibly select the illusion material and design the corresponding geometric dimensions.The simulation and experimental results show that when a layer of designed illusion material applied to the original target A,the detector from the outside could detect the thermal characteristics of the illusion target B,so as to achieve a good interfe-rence effect.The research not only provides a feasible new method for realizing the target stealth by using the thermal metamaterial,but also greatly reduces the difficulty of the preparation of the material.
