Researchers 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 …

Bi-2212 is the only cuprate superconductor that can be made in round wire with high critical current density Jc; however, to date, its use in superconducting magnets is restricted because gas bubbles form during heat treatment, causing wire expansion, leakage and superconducting filament dedensification that greatly reduces Jc in coil length wires. This year we …
Most metals — from the steel used to build bridges and skyscrapers to the copper and gold used to form wires in microchips — are made of crystals: orderly arrays of molecules forming a perfectly repeating pattern. In many cases, including the examples above, the material is made of tiny crystals packed closely together, rather …
