Dashing the dream of ideal 'invisibility' cloaks for stress waves

Whether Harry Potter's invisibility cloak, which perfectly steers light waves around objects to make them invisible, will ever become reality remains to be seen, but perfecting a more crucial cloak is impossible, a new study ...

Updating high-resolution MRI

How can you make a high-frequency MRI machine more precise? By taking an electrical engineering approach to creating a better, uniform magnetic field.

Beyond good vibrations: New insights into metamaterial magic

If invisibility cloaks and other gee-whiz apps are ever to move from science fiction to science fact, we'll need to know more about how these weird metamaterials actually work. Michigan Tech researcher Elena Semouchkina has ...

Invisibility cloak closer to becoming a reality

Photonics is a rapidly growing field in which some of the most sci-fi ideas of the not-so-distant past, are taking form. Now EU-funded research is bringing the notion of an invisibility cloak closer by using microscopic structures ...

Nanoparticles could spur better LEDs, invisibility cloaks

In an advance that could boost the efficiency of LED lighting by 50 percent and even pave the way for invisibility cloaking devices, a team of University of Michigan researchers has developed a new technique that peppers ...

Scientists make new high-tech liquid materials

Scientists at The Australian National University (ANU) have controlled wave-generated currents to make previously unimaginable liquid materials for new technological innovations, including techniques to manipulate micro-organisms.

New invisibility cloak to conceal objects in diffusive atmospheres

Researchers at the Public University of Navarre (NUP/UPNA) and the Universitat Politècnica de València (UPV) have come up with a new invisibility cloak capable of concealing objects in diffusive atmospheres, not just in ...

Invisibility cloak with photonic crystals
