Novel ‘Cloaking Device’ Invented by U of T Researchers

A functioning invisibility cloak has been invented by two members of U of T's Edward S. Rogers Sr. Department of Electrical &Computer Engineering and Professor George Eleftheriades and PhD student Michael Selvanayagam used the principle

The functioning model of the device has been invented by the scientists to publish their research for about $2,000. Radio devices have the property that they can read the appearance and the position of objects by interpreting the waves that jumps after striking the object.

The main phenomenon behind the cloaking device is that it cancels out the waves that bounce off the objects, making an object invisible in the radio spectrum. The cloaking device also has the power to alter the appearance and the location of the objects with the help of the radar.

The first cloaking device was invented by researchers at Duke University in 2006. They were the first scientists, who presented the idea of cloaking and proved it real with the help of specially designed materials.

These scientists were facing some problems regarding the scalability and complexity of the meta-materials that are used to design cloaking device. But, these problems are now resolved by Eleftheriades and Selvanayagam.

The new cloaking device designed by them is flexible and scalable and can be reused with different wavelengths.
