Light, sound, and now, heat—just as optical invisibility cloaks can bend and diffract light to shield an object from sight, and specially fabricated acoustic metamaterials can hide an object from sound waves, a recently ...
(Â鶹ÒùÔº)—It was another good week for physics as a team with members from Germany, Austria and Australia conducted the most precise test of Lorentz symmetry for a photon and found that the speed of light is, indeed, constant—no ...
Invisibility cloaks are a staple of science fiction and fantasy, from Star Trek to Harry Potter, but don't exist in real life, or do they? Scientists at the U.S. Department of Energy (DOE)'s Lawrence Berkeley National Laboratory ...
While people may have never heard of photonics before, they will surely have heard about the technology that relies on its existence, namely the internet, computers and smartphones.
Materials that locally amplify or absorb light allow surprising new kinds of light waves – this has now been shown by calculations at TU Wien (Vienna).
Have you ever wished you could hide under an invisibility cloak like Harry Potter or conceal your car with a Klingon cloaking device like in Star Trek? In a special Thursday bonus episode of Reactions, we celebrate the International ...
When a sound wave hits an obstacle and is scattered, the signal may be lost or degraded. But what if you could guide the signal around that obstacle, as if the interfering barrier didn't even exist? Recently, researchers ...
(Â鶹ÒùÔº)—Today's photonic and plasmonic devices – the latter based on surface plasmons (a coherent delocalized electron oscillations that exist at the interface between metal and dielectric) and combining the small ...
Researchers have developed a new design for a cloaking device that overcomes some of the limitations of existing "invisibility cloaks." In a new study, electrical engineers at the University of California, San Diego have ...
HIV, or human immunodeficiency virus, is the retrovirus that leads to acquired immunodeficiency syndrome or AIDS. Globally, about 35 million people are living with HIV, which constantly adapts and mutates creating challenges ...
