World's First Acoustic Field Rotator May Help Improve Imaging Capabilities Of Medical Ultrasound Devices
2014-02-26 15:35:43

American Institute of Physics A Chinese-U.S. research team is exploring the use of metamaterials -- artificial materials engineered to have exotic properties not found in nature -- to create devices that manipulate sound in versatile and unprecedented ways. In the journal Applied Physics Letters, the team reports a simple design for a device, called an acoustic field rotator, which can twist wavefronts inside it so that they appear to be propagating from another direction. "Numerous...

Invisibility Cloak For Thermal Flow Constructed By Researchers
2013-05-08 15:09:27

Karlsruhe Institute of Technology By means of special metamaterials, light and sound can be passed around objects. KIT researchers now succeeded in demonstrating that the same materials can also be used to specifically influence the propagation of heat. A structured plate of copper and silicon conducts heat around a central area without the edge being affected. The results are presented in the Physical Review Letters journal. “For the thermal invisibility cloak, both materials...

Duke University Engineers Create Invisibility Cloak With 3D Printer
2013-05-06 15:11:00

Lee Rannals for redOrbit.com — Your Universe Online Duke University engineers are developing a way for you to create your own visibility cloak with a 3D printer. Three-dimensional printing is growing in popularity, and the cost for a MakerBot Replicator 2 is now just $2,199. Scientists are also working harder and harder to turn Harry Potter's invisibility cloak into a reality. A group wrote in the New Journal of Physics in March about how they developed a new cloak that is able...

Metascreen Makes Invisibility Cloaks A Potential Reality
2013-03-26 18:29:53

Lee Rannals for redOrbit.com — Your Universe Online Harry Potter had one, and maybe one day so will you, if the new invisibility cloak method described in the New Journal of Physics comes to fruition. US researchers have developed a new cloak that is just micrometers thick and is able to hide three-dimensional objects from microwaves in their natural environment, in all directions from all the observers' positions. Previously, scientists have developed invisibility cloaks that...

Lee Rannals for redOrbit.com — Your Universe Online Invisibility cloaking may one day help to shield ships floating around in the ocean from waves, according to research presented at the Annual Meeting of the American Physical Society (APS). The new approach to invisibility cloaking is based on the influence of the ocean floor's topography on various "layers" of ocean water. Reza Alam, assistant professor of mechanical engineering at the University of California,...
