Engineers and scientists at The University of Texas at Austin and the AMOLF institute in the Netherlands have invented the first mechanical metamaterials that easily transfer motion effortlessly in one direction while blocking it in the other, as described in a paper published on Feb. 13 in Nature. The material can be thought of as a mechanical one-way shield that blocks energy from coming in but easily transmits it going out the other side.

Four Texas ECE faculty were recognized in Thomson Reuters’ list of Highly Cited Researchers in 2015 for exceptional impact in their fields. They are Prof. Jeffrey Andrews, Prof. Al Bovik, Prof. Robert Heath, and Prof. Sriram Vishwanath. This is the second consecutive year on the list for all four researchers.

Andrea Alù and Mikhail Belkin in the Department of Electrical and Computer Engineering at the Cockrell School of Engineering at The University of Texas at Austin have created a new nonlinear metasurface, or meta mirror, that could one day enable the miniaturization of laser systems.

Six professors and one adjunct associate professor from the Cockrell School of Engineering have been included in the Thomson Reuters list of Highly Cited Researchers for 2014. This list recognizes many of the world’s leading scientific minds, and the strong Cockrell School representation illustrates UT Austin’s growing influence on the global research landscape. Four of these professors come from the Deprtment of Electrical and Computer Engineering (UT ECE) and the Wireless Networking and Communications Group (WNCG).
