New route to design a practical invisibility cloak

With the emergence of metamaterials and transformation optics in the past few years, invisibility has become a scientific possibility that has attracted sustainable research interest.

Thin, active invisibility cloak demonstrated for first time

Invisibility cloaking is no longer the stuff of science fiction: two researchers in The Edward S. Rogers Sr. Department of Electrical & Computer Engineering have demonstrated an effective invisibility cloak that is thin, scalable and adaptive to different types and sizes of objects.

Invisibility cloak moves forward with 3D printing

Seven years ago, Duke University engineers demonstrated the first working invisibility cloak in complex laboratory experiments. Now it appears creating a simple cloak has become a lot simpler.

Scientists build an uber-thin invisibility cloak

Invisibility cloaks proposed by modern day scientists are still typically fairly bulky contraptions – which poses an obvious issue for those interested in designing Harry Potter-style applications.

Reversing Doppler Effect holds promise for invisibility cloak

If scientists carry on at this rate, we'll soon have more types of invisibility cloak to choose from than Imelda Marcos had shoes.

New 'invisibility cloak' works with visible light

St Andrews University physicists have produced a new material that they say could form the basis of a Harry Potter-style invisibility cloak.
