Biography

Andrea Alù’s seminal research on metamaterials is impacting a broad range of scientific disciplines, including electromagnetics, radio science, nano-optics, photonics, and acoustics. Metamaterials are engineered to have properties not found in natural materials and can block, absorb, enhance, or bend electromagnetic waves at will. Alù pioneered plasmonic cloaking and mantle cloaking, showing that a metamaterial layer can be designed to largely suppress the scattering of an object in all directions. This has important implications for radar camouflaging and invisibility. His work on momentum biasing to break the natural symmetry with which waves travel in common materials has enabled magnet-free circulators and isolators. This presents exciting opportunities for full-duplex radio communications, cheaper and lighter radar and sonar technology, and improved ultrasound imaging.

An IEEE Fellow, Alù is the Einstein Professor of Physics and founding director of the Photonics Initiative at the City University of New York Advanced Science Research Center, New York, NY, USA.
