Harnessing the unique properties of metamaterials, researchers in China have recently published a work detailing the implementation of a thin air, broadband and remotely controllable 'invisible gateway' that is able to shield all types of electromagnetic waves while letting through all other physical objects.

Researchers at the Universitat Autonoma de Barcelona have recently designed a peculiar material — called a dc metamaterial — that has the property of making objects wrapped in it undetectable to magnetic and very low-frequency electromagnetic fields. The breakthrough brings the dream of "invisibility cloaking" closer to reality and could have important repercussions in both the military and medical fields. Read More

Harry Potter and his cloak of invisibility - which you can't see obviously

Invisibility has been a staple of science fiction, (and my own personal fantasies), for decades and in recent years we’ve watched as fiction edges ever closer to reality through the use of metamaterials. The problem with most of the devices currently being researched however, is that since they totally encompass the object being rendered invisible, they are also rendered blind as well, which kind of defeats the purpose. But a team from Hong Kong’s University of Science and Technology believes they have come up with an answer to this problem and that it is indeed possible to create a cloaking device that would be able to render an object invisible without encompassing it.

Development in metamaterials - the so called “left handed” composite materials that negatively refract light waves and promise the sci-fi scenario of rendering objects invisible - is accelerating with news this week of two breakthroughs from scientists at the University of California, Berkeley.
