Discovery at UAB brings us nearer to making the dream of invisibility true
A group of researchers from the Department of Physics at UAB have designed a device, called a dc metamaterial, which makes objects invisible under certain light -- very low frequency electromagnetic waves - by making the inside of the magnetic field zero but not altering the exterior field. The device, which up to date has only been studied in theoretical works, thus acts as an invisibility cloak, making the object completely undetectable to these waves. (2009-07-07)

KIT researchers protect the princess from the pea
In the past years, invisibility cloaks were developed for various senses. Objects can be hidden from light, heat or sound.

The results are now presented in the renowned Nature Communications journal. (2014-06-20)

Extremely small magnetic nanostructures with invisibility cloak imaged
In novel concepts of magnetic data storage, it is intended to send small magnetic bits back and forth in a chip structure, store them densely packed and read them out later.

In this fashion, the magnetic stray field can be reduced in a fashion allowing for small yet mobile bits. (2018-10-18)
