The acoustic cloaking device works in all three dimensions ... Bogdan Popa, a research scientist in electrical and computer engineering, shows off the 3D acoustic cloak he helped design and build as a ...

As Cummer puts it, "we didn't come up with this overnight." Research scientist Bogdan Popa with a 3D acoustic cloaking device constructed with components created in a 3-D printer (Photo ...

Some rather clever engineers have created the world's first 3d-cloaking device. The pyramid-esque structure reroutes sound waves creating the impression that an object beneath is simply not there.

Duke University engineers have demonstrated the world’s first three-dimensional acoustic cloak, a device that reroutes sound waves to create the impression that the cloak and anything beneath it are ...

If this latest metalens advance can be rapidly applied to metamaterial cloaks, an optical, 3D cloaking device may become a reality in humanity's very near future.

but Choi and Howell's device is more than just a variation on the classic magician's trick (which uses carefully-placed mirrors). It can be scaled up or down to fit any cloaking size (on the ...

But by using a few perforated sheets of plastic and a complex algorithm, researchers at Duke University have developed the world’s first 3D acoustic cloaking device. The device escapes acoustic ...

US researchers have unveiled two different approaches to 3D cloaking that they say is a significant step towards fabricating practical cloaking devices. In the Nature paper, the Berkeley researchers ...
