Scientists from Harvard University and the University of Leeds recently demonstrated a new terahertz semiconductor laser capable of emitting beams with a much smaller divergence than conventional terahertz laser sources. The collaborative study suggests several future applications, all relying on ...
Dream No More – the Invisibility Cloak is Here
Researchers from Berkeley Labs at the University of California have successfully developed a “carpet cloak” using nanostructured silicon that could eliminate the impression of an object placed underneath it. Even though the cloak itself remains visible, the protrusion created by ...
Bending Light the Wrong Way
A Princeton University research team has recently created an easy-to-produce material that has the rare ability to bend light in the opposite direction from all naturally occurring materials. This new substance belongs to the relatively new class of materials called ...
