Metamaterial-Enhanced TechnologyWe have been exploring several ways in which metamaterials can advance real-life technology, from highly efficient opto-electronics (see our MURI effort) to energy harvesting, sensing, radio-wave and optical antennas and metasurfaces.
Cloaking and InvisibilityOne of the most exciting applications of metamaterials: our group has pioneered the use of plasmonic and mantle cloaks for drastic scattering suppression of radio-waves, infrared, matter, sound and light waves.
Plenary talk at SPIE Optics & Photonics (2016)
Non-Reciprocity and TopologyOur group has been exploring several exciting concepts to exploit symmetry-breaking to enable extreme wave phenomena (see our MURI effort), including large non-reciprocity and topological metamaterials for light and sound.
Multi-Physics MetamaterialsWe have been exploring multi-physics platforms to extend the playground of opportunities enabled by metamaterials for technology, including opto-mechanical phenomena, thermal effects, plasmonics and polaritonics.
Welcome to Andrea Alù’s research group webpageAndrea Alù is the founding director of the Photonics Initiative at the CUNY Advanced Science Research Center, Einstein Professor of Physics at the CUNY Graduate Center, and Professor of Electrical Engineering at The City College of New York. He is affiliated with the Wireless Networking and Communications Group and the Applied Research Laboratories, both based at the University of Texas at Austin, where he is a Senior Research Scientist and Adjunct Professor. His research interests span over a broad range of technical areas, including applied electromagnetics, nano-optics and nanophotonics, microwave, THz, infrared, optical and acoustic metamaterials and metasurfaces, plasmonics, nonlinearities and nonreciprocity, cloaking and scattering, acoustics, optical nanocircuits and nanoantennas.
