Chiral anomaly materials (CAM, e.g., axion insulator, topological insulator and some of Weyl semimetal) are new states of quantum matter. Anomalous Hall effect can occur in CAM, the anomalous Hall effect is closely related to the topological magneto-electric effect, i.e., when an electric field is applied to CAM, not only the electric field is induced, but also the magnetic field, vice versa. According to those properties, we design an electric cloak with quantized CAM and conductor, and a magnetic cloak with quantized CAM and superconductor. Simulation and calculation results show that the electric cloak can cloak applied electric field and induce magnetic field, and the magnetic cloak can cloak applied magnetic field and induce electric field. When applied electric field is generated by a point charge, the monopole can be obtained.
手性反常材料（CAM，如轴子绝缘体、拓扑绝缘体和部分外尔半金属）是量子物质的新状态。反常霍尔效应可以在 CAM 中发生，反常霍尔效应与拓扑磁电效应密切相关，即当电场作用于 CAM 时，不仅会感应出电场，还会感应出磁场，反之亦然。根据这些特性，我们设计了一种由量化 CAM 和导体组成的电斗篷，以及一种由量化 CAM 和超导体组成的磁斗篷。模拟和计算结果表明，电斗篷可以掩盖外加电场并感应磁场，而磁斗篷可以掩盖外加磁场并感应电场。当外加电场由点电荷产生时，可以获得磁单极子。
