1306.6835 (Hongyi Xu et al.)

Experimental demonstration of an ultra-thin three-dimensional thermal

Hongyi Xu, Xihang Shi, Fei Gao, Handong Sun, Baile Zhang
We report the first experimental realization of a three-dimensional thermal cloak shielding an air bubble in a bulk metal without disturbing external thermal flux. The cloak is made of a thin layer of homogeneous and isotropic material with simple mechanical manufacturing. The thickness of cloak is 200 um while the cloaked air bubble has a diameter of 1 cm, achieving the ratio between dimensions of the cloak and the cloaked object 2 orders smaller than previous thermal cloaks which were mainly realized at a two-dimensional plane. This work can find applications in novel thermal devices in the three-dimensional physical space.
