USA Today has a new article about invisibility cloaks! It is very interesting. Here are some highlights.

One of the new prototypes is a woven fishnet of silver nanowires, each one about 10,000 times thinner than a human hair. It was reported this week in the journal Science. The team tested the device for red, or visible, light and infrared light and said the prototype bends red light from all angles hundreds of times more effectively than in past attempts.

The other device, reported this week in Nature magazine, relies on 21 stacked grids of silver and magnesium fluoride of similarly small sizes. The researchers found that the device bent infrared light around the grids.

And unlike Harry Potter’s cloak, these fragile metamaterials would be blown away by the gentlest breeze. “Developing a way to manufacture these materials on a large scale will also be a challenge.
