Metamaterials and plasmonics offer unprecedented opportunities to tailor and enhance the interaction of waves with materials. In this talk, I discuss our recent research activity in electromagnetics, nano-optics and acoustics, showing how suitably tailored meta-atoms and suitable arrangements of them open exciting venues to manipulate and control waves in unprecedented ways.
I will discuss our most recent theoretical and experimental results, including nanostructures and metasurfaces to control wave propagation and radiation, large nonreciprocity without magnetism, giant nonlinearities in properly tailored metamaterials, and parity-time symmetric meta-atoms and metasurfaces. Physical insights into these exotic phenomena, new devices based on these concepts, and their impact on technology will be discussed during the talk.
Bio: Andrea Alù is an Associate Professor and the David & Doris Lybarger Endowed Faculty Fellow in Engineering at the University of Texas at Austin. He received his PhD from the University of Roma Tre, Italy, in 2007 and, after a postdoc at the University of Pennsylvania, he joined the faculty of the University of Texas at
Austin in 2009.
His current research interests span over a broad range of areas, including metamaterials and plasmonics, electromagnetics, nano-optics, photonics and acoustics. Dr. Alù is a Fellow of IEEE, OSA, and APS, and has received several scientific awards, including the NSF Alan T. Waterman award (2015), the OSA Adolph Lomb Medal (2013), and the URSI Issac Koga Gold Medal (2011).
