(Phys.org)—Researchers have created a dc invisibility cloak made of a metamaterial that not only shields an object almost perfectly, but at 1-cm thick is also the thinnest cloak ever constructed, reaching the ultimate limit ...
(Phys.org)—A general property of magnetic fields is that they decay with the distance from their magnetic source. But in a new study, physicists have shown that surrounding a magnetic source with a magnetic shell can enhance ...
(PhysOrg.com) -- Researchers have proposed a new design for an invisibility cloak - a device that could make objects invisible by guiding light around anything placed inside the cloak.
Autonomous University of Barcelona researchers, in collaboration with an experimental group from the Academy of Sciences of Slovakia, have created a cylinder which hides contents and makes them invisible to magnetic fields. ...

In 1897, H.G. Wells created a fictional scientist who became invisible by changing his refractive index to that of air, so that his body could not absorb or reflect light. More recently, Harry Potter disappeared from sight ...

(Phys.org)—Typically when two magnets are brought close together, they either attract or repel each other due to interactions between their magnetic fields. In a new study, researchers have designed a 3D magnetic invisibility ...
(PhysOrg.com) -- From Tolkien's ring of power in The Lord of the Rings to Star Trek's Romulans, who could make their warships disappear from view, from Harry Potter's magical cloak to the garment that makes players vanish ...
