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.

IRVINE, Calif. – June 5, 2015 – The University of Texas at Austin graduate student Yingzhe Li presented innovative engineering research at the fourth annual Broadcom Foundation University Research Competition sponsored by Broadcom Foundation, a non-profit funded by Broadcom Corporation (NASDAQ: BRCM). Li’s project is titled “A Stochastic Geometry Approach to the Coexistence of LTE and Wi-Fi in Unlicensed Spectrum.”
