Until now, the invisibility cloaks put forward by scientists have been bulky devices - an obvious flaw for those interested in Harry Potter-style applications. However, researchers at The University of Texas at Austin have developed a cloak that is just micrometers thick and can hide three-dimensional objects from microwaves in their natural environment, in all directions and from all of the observers’ positions.
“The Invisible Man,” H.G. Wells’ 1881 novella, describes invisibility and invisibility cloaking concepts that are currently being explored and discovered at the Cockrell School of Engineering. Department of Electrical and Computer Engineering assistant professor Andrea Alú uses Wells’ story as a base for explaining his unique and innovative cloaking technique to make three-dimensional objects invisible. Alú takes “The Invisible Man” approach in his February TedxAustin talk.

Dr. Seth Bank's research into III-V compound semiconductors could cool down your laptop, increase the capacity and speed of fiber-optics, and make solar cells more efficient. Bank hopes to improve III-V compound semiconductors—used for everything from cell phone transistors to LED's in traffic lights—by embedding semi-metal nanoparticles in them.
