“…Our proposed method is directly obtained from Laplace equations and is much simpler and more effective than the methods reported yet for bifunctional multishell cloaking. To illustrate the efficiency of our method we have investigated the ideal, inhomogeneous shell and composite material background approaches for the bifunctional multishell cloaking phenomenon [57]. Theoretical analysis of these approaches is discussed in detail in the following three cases.…”

This article is a review of the advances and progresses in the field of heat cloaking which is being realized using metamaterials. Heat cloaking has been a particularly important subject of study due to its potential multidimensional applications. The process which manipulates the heat flux in such a way that it can neither enter into the cloaked region nor be distorted outside is called thermal cloaking. Transformation optics has made the hitherto inconceivable advancements in the field of thermodynamics possible with the remarkable assistance of metamaterials. In this article we present a review of the work done in the field of heat cloaking, its progress and outlook. We discuss the theoretical and experimental studies, models, design managements, implementations and behaviors of thermal invisibility cloaking and related devices. This review is intended to help further develop practical and applicable concepts, examine fabrication techniques for a variety of different invisibility cloaking devices and systems, and to pave a way for the new avenues leading to new future technologies.

“…Many achievements of invisibility cloak have been motivated thanks to the pioneering theoretical work. [1][2][3][4] Inspired by those theoretical works, varieties of electromagnetic cloak, [5][6][7][8][9][10][11] acoustic cloak, [12][13][14] matter wave cloak, 15 mass diffusion cloak, 16 heat cloak, [17][18][19][20] magnetic cloak, [21][22][23] dc electric cloak [24][25][26] have been demonstrated in the past few years. It is very difficult to construct a perfect invisible electromagnetic cloak by natural material, for it requires anisotropic medium.…”

When an electric field is applied on a topological insulator, not only the electric field is generated, but also the magnetic field is generated, vice versa. I designed topological insulator and superconductor bi-layer magnetic cloak, derived the electric field and magnetic field inside and outside the topological insulator and superconductor sphere. Simulation and calculation results show that the applied magnetic field is screened by the topological insulator and superconductor bi-layer, and the electric field is generated in the cloaked region. © 2017 Author (s)

“…Many achievements of invisibility cloak have been motivated thanks to the pioneering theoretical work 1 – 4 . Inspired by those theoretical works, varieties of electromagnetic wave cloak 5 – 11 , acoustic wave cloak 12 – 14 , matter wave cloak 15 , mass diffusion cloak 16 , heat diffusion cloak 17 – 20 , magnetic cloak 21 – 23 , electric cloak 24 – 26 have been theoretically designed and experimentally demonstrated. Generally speaking, it is difficult to construct a perfect invisible electromagnetic wave cloak by natural material, for it requires inhomogeneous and anisotropic material, yet a perfect dc electric cloak can be fabricated from natural material.…”

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.
