隐形传感器：多物理场的同时传感和再现
Invisible sensor: Simultaneous sensing and camouflaging in multiphysical fields
摘要：
在一个单一的设备中操纵各种类型的物理信号一直吸引着科学家和工程师的注意力。然而，这是非常具有挑战性的，如果不是不可能的，即使是新兴的超材料。到目前为止，已经提出了许多人工材料，理论上和（或）实验上，用于操纵各种波/信号的一个功能一个设备的基础上。在这项工作中，第一次，我们采用未经装饰的天然材料，实验证明了在同一设备上的热电流和直流电流的同时伪装。它展示了独创性如何克服自然材料系统的局限性，而不需要复杂的装饰来赋予非均匀和（或）各向异性特性，这在以前被认为是不可能实现的，除非使用超材料。
英文摘要：
To manipulate various types of physical signals in one single device has long captivated the attention of scientists and engineers. This however is very challenging, if not impossible, even for emerging metamaterials. Up to date, many artificial materials have been proposed, theoretically and (or) experimentally, for manipulating various waves/signals on a one-function-one-device basis. In this work, for the very first time, we employ undecorated natural materials to experimentally demonstrate a simultaneous camouflage for thermal current and electric dc current on the same device. It demonstrates how ingenuity can overcome the limitations of natural material systems without the need for complex decoration to impart inhomogeneous and (or) anisotropic properties, which was previously considered impossible to accomplish except by using metamaterials.
