最近提出直流超材料的概念后，隐藏静磁场正在成为现实。在这里，我们通过基于超导第一原理的模型，对由平行方形超导薄板组成的直流超材料的磁化率进行了精确而系统的计算。由于同时考虑了磁能和动能，我们的模型考虑了超导体中穿透深度的影响，因此可以应用于高温超导体。因此，从计算结果来看，可以基于高温超导薄膜构建能够隐藏静磁场的装置。
Cloaking a static magnetic field is becoming a real possibility after the recently proposed concept of dc metamaterials. Here, we present, by a model based on superconductivity first principles, accurate and systematic calculations for the susceptibility of a dc metamaterial consisting of parallel square superconducting thin plates. Since both magnetic and kinetic energies are considered, our model takes into account the effect of a penetration depth in the superconductors and therefore can be applied for high-temperature superconductors. Thus, from the calculated results, a device that can cloak a static magnetic field may be constructed based on high-temperature superconducting thin films.
