论文摘要
导电矩阵中的不均匀性变形了施加的电流的流动模式。通常的电流斗篷可以定义为对不均匀性的矩阵特性的永久修改，以确保当前流动模式在通过修饰区域之前和经过后相似，因此这意味着不均匀区域的“电气隐形”。在这里，我们介绍了当前的斗篷的概念，该斗篷可以通过外部字段上的方式调整（例如开关）。我们通过分析表明并使用有限元模拟证明，可以通过外部磁场来构建和操纵电流斗篷，以用于混凝土系统，该混凝土系统由具有不锈钢包含的磁性抗性基质组成。
An inhomogeneity into a conductive matrix deforms the flow pattern of an applied electric current. A usual current cloak can be defined as a permanent modification of the matrix properties around the inhomogeneity guaranteeing that the current flow pattern is similar before and after passing by the modified zone, so it implies the "electrical invisibility" of the inhomogeneous region. Here we introduce the concept of a current cloak that can be tuned --switched on and off, for example-- by means on an external field. We demonstrate analytically and using Finite Elements Simulations that a current cloak can be constructed and manipulated by an external magnetic field for a concrete system consisting in a magneto-resistive matrix with a stainless steel inclusion.
