基于无源和有源方案的电场和温度场同时控制
Simultaneous Manipulation of Electric and Thermal Fields via Combination of Passive and Active Schemes
摘要：
隐身衣由于其新颖的物理场操纵概念而受到越来越多的关注。然而，它通常是通过单一的方案（即被动或主动方案）来实现的，并且局限于单一领域。本文提出了一种通过被动和主动相结合的方法实现多物理场同时操控的一般方法。在实验上，通过同时操纵电场和热场，证明了这种方法。首先，设计了一种同时具有电隐身和热隐身功能的装置。其次，另一种装置被证明同时作为电隐身衣和热集中器。实验结果与仿真结果吻合较好，验证了该方法的可行性。我们的方法也可以推广到其他多物理场领域，这将为新系统的设计创造更大的自由度，并可能在广泛的领域中实现新的潜在应用。
英文摘要：
Increasing attention has been focused on the invisibility cloak due to its novel concept for manipulation of physical field. However, it is usually realized by single scheme (namely passive or active scheme) and limited in a single field. Here, we proposed a general method to achieve simultaneous manipulation of multi-physics field via combination of passive and active schemes. Experimentally, this method was demonstrated by simultaneous manipulation of electric field and thermal field. Firstly, a device was designed to simultaneously behave as electric and thermal invisibility cloak. Secondly, another device was demonstrated to simultaneously behave as electric invisibility cloak and thermal concentrator. The experimental results agree well with the simulated ones, confirming the feasibility of our method. Our method can also be extended to the other multi-physics fields, which would create much more freedom to design of new system and might enable new potential application in broad areas.
