The camouflage phenomenon (invisibility or illusion) of thermodynamics has attracted great attentions and many experimental demonstrations have been achieved by virtue of simplified approaches or the scattering cancellation. However, all of the experiments conducted are limited in the invisibility of spheres or two-dimensional (2D) cylinders. An ellipsoid camouflage device with a homogenous and isotropic shell is firstly reported based on the idea of the neutral inclusion and a 2D elliptical thermal camouflage device is realized by a thin-layer cloak of homogeneous isotropic material firstly. The robustness of this scheme is validated in both 2D and 3D configurations. The current work may provide a new avenue to the control of the thermal signatures and we believe this work will broaden the current research and pave a new path to the control of the path of the heat transfer.
热力学的伪装现象（不可见性或错觉）已引起了极大关注，并且借助简化方法或散射消除已实现了许多实验演示。然而，所有已进行的实验都局限于球体或二维（2D）圆柱体的不可见性。基于中性包含体的概念，首次报道了一种具有均匀各向同性外壳的椭球体伪装装置，并且首次通过均匀各向同性材料的薄层隐身衣实现了二维椭圆形热伪装装置。该方案的稳健性在二维和三维配置中均得到了验证。当前的工作可能为控制热信号提供一条新途径，并且我们相信这项工作将拓宽当前的研究范围，并为控制热传递路径开辟一条新道路。
