We theoretically demonstrate how cloaks, anticloaks, magnifiers and illusion devices can be devised for the case of static magnetic fields. For some of these devices, we make use of the concept of negative permeability materials. Because these materials can be emulated in practice by sets of currents, our results may provide the recipe for the experimental realization of novel devices for controlling...
Metamaterials have introduced many relevant new possibilities in the manipulation of light, microwaves, sound waves, and other systems. In many cases, the design and optimization of metamaterials has been achieved in conjunction with the mathematical technique of transformation optics, which allows one to guide rays of light or electromagnetic fields along desired directions. This is achieved by tailoring...
Metamaterials have made possible many breakthroughs like electromagnetic cloaks or perfect lenses. In an interesting line of research, metamaterials have been used to simulate celestial objects that were thought to be impossible to replicate at the human scale. For example, the analogous of optical black holes has been theoretically and experimentally realized based on metamaterials. One of the most...
