Extreme Control of Light and Sound with Metasurfaces

Date: 22nd June 2022
Time: 11:00 am - 12:00 pm
Location: Online AEST
Online | TMOS Colloquium

Dr. Andrea Alù will speak about using metasurfaces to explore extreme wave phenomena. This in turn can be used to manipulate light and sound at the nano-scale. Wave controllability is highly desired for its applications in areas such as astronomy, engineering, oceanography, physics, and fiber optics, to name a few.

The presentation will explore the role of broken symmetries, geometrical rotations, and strong wave-matter interactions in polaritonic systems. This in turn opens new opportunities for classical and quantum wave manipulation. These findings open opportunities to tailor waves in robust and efficient ways, controlling their propagation, breaking Lorentz reciprocity, and enabling topological order and phase transitions. Fundamental concepts of this emerging research will be discussed, and their impact on practical technologies, from imaging and sensing to computing.


Dr. Andrea Alù is a Distinguished Professor at the City University of New York (CUNY), the Founding Director of the Photonics Initiative at the CUNY Advanced Science Research Center, and the Einstein Professor of Physics at the CUNY Graduate Center. He received his Laurea (2001) and PhD (2007) from the University of Roma Tre, Italy, and, after a postdoc at the University of Pennsylvania, joined the faculty of the University of Texas at Austin in 2009, where he was the Temple Foundation Endowed Professor until January 2018.

Dr. Alù is a Fellow of NAI, AAAS, IEEE, OSA, MRS, SPIE, and APS, and has received several scientific awards, including the Blavatnik National Award in Physical Sciences and Engineering, the IEEE Kiyo Tomiyasu Award, the Vannevar Bush Faculty Fellowship, and the NSF Alan T. Waterman award.
