Invisibility cloaking is no longer the stuff of science fiction: two researchers in The Edward S. Rogers Sr. Department of Electrical & Computer Engineering have demonstrated an effective invisibility cloak that is thin, scalable and adaptive to different types and sizes of objects.

Professor George Eleftheriades and PhD student Michael Selvanayagam have designed and tested a new approach to cloaking—by surrounding an object with small antennas that collectively radiate an electromagnetic field. The radiated field cancels out any waves scattering off the cloaked object. Their paper ‘Experimental demonstration of active electromagnetic cloaking’ appears today in the journal Physical Review X.

A recent study investigating the side effects of hydraulic fracturing has found higher than normal levels of radioactivity, along with other contaminants such as salts and metals, in the waters of Blacklick Creek in Western Pennsylvania.

The report, which was published recently in the journal Environmental Science and Technology, analyzed sediments found in river water near a fracking waste water plant, and discovered 200 times more radium than one would expect to find in nature.
