双层结构中电场和温度场的独立控制

Independent Manipulation of Electric and Thermal Fields with Bilayer Structure

Chuwen Lan, Xianglong Yu, Lingling Wu, Bo Li, Ji Zhou

摘要:

近年来,利用相变材料和超材料对各种物理场进行操控的研究越来越受到人们的关注,这需要复杂的结构,并且通常局限于单个场。在这里,我们第一次提出并实验证明了双层结构,以实现同时独立的多物理场(直流电场和热)直接求解直流电/热场方程的操纵。该结构由两层组成:外层由各向同性均质材料制成,内层为扇形层。由于它不是基于TO,它可以很容易地用自然发生的材料实验制造。在实验上,我们设计,制造和表征两种结构同时表现为直流电斗篷/热集中器和直流电集中器/热斗篷,分别。仿真结果与实验结果吻合较好,从而证实了我们的方法的可行性。这项工作为多物理场的操纵提供了一条新的途径,因此可能在各个领域中找到潜在的应用。

英文摘要:

Recently, increasing attention has been focused on the employment of transformation and metamaterial for manipulation of various physical fields, which requires complicated configuration and usually limits in single field. Here, for the first time, we propose and experimentally demonstrated bilayer structure to achieve simultaneously independent manipulation of multi-physics field (dc electric fields and thermal) by directly solving the dc electric/ thermal field equations. This structure is composed of two layers: the outer layer is made of isotropic and homogeneous material, while the inner layer is fan-shape layer. Since it is not based on TO, it can be readily experimentally fabricated with naturally occurring materials. Experimentally, we has designed, fabricated and characterized two structures simultaneously behaving as dc electric cloak/ thermal concentrator and dc electric concentrator/ thermal cloak, respectively. The simulation results agree well with the experiment ones, thus confirming the feasibility of our methodology. This job provides a novel avenue to manipulation of multiphysics fields, thus might find potential applications in various areas.
