Since the Harry Potter books first hit bookshelves, the world has been getting little pieces of J.K. Rowling’s universe. Universal Studios allows you to explore Diagon Alley, you can make your own butterbeer at home, and maybe, in your lifetime, you can experience a working invisibility cloak.
Scientists now have a way to cloak something very small, making it effectively invisible. But what if scientists and engineers created a much larger version? What if we all had access to invisibility cloaks?
The latest model of the Invisibility Cloak is here, and it has two major improvements on the last few models. It can actually wrap around the stuff it’s concealing — and you can’t see the cloak itself. Take a look!
If you’re a non-magical being, you might think your chances of becoming invisible are slim to nil. But don’t jump to conclusions just yet: Researchers are now claiming to have developed a portable system that can make small objects, like your keys or pet lizard, disappear from sight.
Metamaterials are a mind-bending class of matter. Broadly defined as manmade materials with unusual properties not found in nature, this category of materials is probably most famous for serving as the building blocks for a Harry Potter-style invisibility cloak. But so much more is possible.
Cylon raider? A new Tron vehicle that we'll see in an upcoming director's cut? Definitive proof that we are not alone? Actually, it's none of those things, but the dead silence it produces is amazing anyway.
Researchers have figured out how to use a specific engraving technique in order to alter the frequency of light a metal—any metal—absorbs or reflects. How? By carving tiny rings, smaller than the wavelengths of light.
Your pervy, Harry Potter-fueled dreams are edging closer to reality, now British scientists have used metamaterials to bend light in a different manner to previous attempts. Now, it works with a greater range of colors.
Invisibility cloak project is back on! It's from a different team of scientists that were using silver-plated nanoparticles in water though, with these latest Harry Potter enthusiasts using photonic metamaterials to change light rays.
No, the opposite of an invisibility cloak isn't a normal jacket, smartass. This universal mirror uses metamaterials to bounce light back at the same angle from which it came, so no matter where you stand, you can see yourself perfectly.
Japan's been tooling around with versions of invisibility cloaks for years now, but they seem to have finally perfected it. Theoretically. By using "left-handed metamaterials" to make electromagnetic control devices, researchers can generate lenses that either reflect no light or have a perfect focal point—the end…
US scientists have finally done it: they've created a cloak to hide an object in the visual light spectrum. The catch? This cloak is just 10 micrometres in diameter and only works in 2D space. But were still excited about the "locker room potential."
