Story:

Invisibility cloaks are the stuff of comic books and science fiction, but a team of scientists at the University of St Andrews may have brought us one step closer to making them a reality. The researchers have developed a new way to cloak objects using infrared light. The cloak, which is made of metamaterials, causes light to flow around an object as if it wasn't there. This is the first time that scientists have been able to create an invisibility cloak using infrared light. The new cloak is also much smaller than previous cloaks, which means that it could be used to cloak small objects such as nanoparticles. This is the first practical breakthrough in a much-theorised area of physics that has inspired characters such as the Invisible Man and Harry Potter.

A new metamaterial developed by a team of researchers led by Dr Andrea Di Falco promises to revolutionize the manipulation of light. The metamaterials used in the cloak are made up of small metal discs that are arranged in a honeycomb pattern. When light hits the cloak, it is deflected around the object, preventing it from being seen. The scientists who developed the cloak say that it could be used to make objects such as planes and tanks invisible to enemies.

This new material has the potential to revolutionize optical technology, including invisibility cloaks and more efficient solar panels. It works by bending light around an object, essentially making it invisible to the naked eye.

Dr Di Falco says that this new material gives us "the ultimate handle on manipulating the behaviour of light". He believes its potential applications are endless and could dramatically change the way we interact with light.
