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.

Join Prof. Andrea Alù as he shares insight into his work with metamaterials, light and an "invisibility cloak." 

WNCG student Sarabjot Singh placed among the top 12 worldwide finalists in the Broadcom Foundation’s annual University Research Competition. The competition rewards innovative graduate students undertaking research at top engineering universities around the world. The 12 finalists presented their work to more than 500 Broadcom Corporation engineers who serve as judges during Broadcom’s Annual Technical Conference. Singh was nominated for the award by his advisor, Prof. Jeffrey Andrews.
