Description:

Prof. 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. 

The field of metamaterials, artificial materials engineered at the nanoscale, has been rapidly evolving in the past two decades, demonstrating extreme optical and acoustic phenomena and unprecedented control over wave propagation. In this talk, he will discuss recent developments in this field of research, with an emphasis on the role of symmetries in establishing emerging optical and acoustic responses for metamaterials based on otherwise simple constituents.
