Potterheads: The Invisibility Cloak Would Soon Be a Reality

“If you could have one superpower, what would it be?”

Invisibility.”

This has always been my answer. Ever since I was a kid. I mean, who would not want to be invisible? You could go anywhere you want, do anything you want and never be seen. You could get into flights and ride first class [*wink*] or watch movies without buying the tickets or simply gawk at people without being termed a ‘psychopath’.

And being the prodigious Harry Potter fan that I am,

I have always wanted that invisibility cloak. Also, I’m sure millions of you have shared this longing of mine. Now it seems like there are people who are working towards making this age-old dream of ours a reality. You can disappear whenever you want and wherever you want. Because as we know it and as J.K.Rowling stated, “Death had an invisibility cloak.”

With our ever advancing innovations and technology, the nerds of Moscow Institute of Technology and Russian Academy of Sciences have formulated a new material. One which refracts light in a bizarre manner. For those who paid the slightest attention in your high school physics classes will know that the incident light usually refracts on the other side of the normal. But this metamaterial causes the refraction of light on the same side of the normal as the incident light. With a little more work done on it, the perfect invisibility cloak would one day be yours!

Researchers at UC Berkeley have also succeeded in designing a cloak made of gold nanoantennas and mirrors which can completely obscure visible light.

“Our ultra-thin cloak now looks like a coat,” said Xiang Zhang, director of the Materials Sciences Division at Berkeley Lab’s. He is also the chief authority of the artificially engineered nanostructures known as “metamaterials”. Metamaterials are synthetic structures which exhibit unusual properties not found in natural substances. Like negative refractive index for example.

While scientists at the University of Tokyo have worked towards something a little different. This technology called optical camouflage which works on the principle that in order to merge with the background, project the background on to yourself. Voila!

All around the globe so many brilliant minds are at work. And all towards one goal, to make our Harry Potter fantasy a reality. It would, quite literally, be a dream come true. So all you Muggles, keep your fingers crossed.

With our never ceasing Potter obsession leading to Marauder’s Map like apps, we can solemnly swear that we are up to no good! 😉
