Seminar Information
In this talk, I discuss our recent efforts in the context of metamaterials pushing the boundaries of wave-matter interactions in mechanics, acoustics and nanooptics. I will discuss our recent results on even and odd Willis coupling in acoustic metamaterials, and their relations to chiral and nonreciprocal wave propagation. These concepts, applicable from macroscopic meta-structures operated at kHz frequencies to nanoscale phenomena driven by phonon resonances, can also be leveraged to induce topological wave phenomena in suitably tailored metamaterials with broken symmetries. During the talk, I will showcase the basic physics underlying these exotic wave phenomena, and various opportunities for wave engineering and technologies.
Andrea Alù is the Founding Director and Einstein Professor at the Photonics Initiative, CUNY Advanced Science Research 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, he joined the faculty of the University of Texas at Austin in 2009, where he was the Temple Foundation Endowed Professor until Jan. 2018. Dr. Alù is a Fellow of NAI, MRS, AAAS, IEEE, OSA, SPIE and APS, and has received several scientific awards, including the Blavatnik National Award for Physical Sciences and Engineering, the AAAFM Heeger Award, the Dan Maydan Prize in Nanoscience, the IEEE Kiyo Tomiyasu Award, the Vannevar Bush Faculty Fellowship from DoD, the ICO Prize in Optics, the NSF Alan T. Waterman award, the OSA Adolph Lomb Medal, the Dan Maydan Prize in Nanoscience, and the URSI Issac Koga Gold Medal.
