From Cloaking to One-Way Mirrors: the Fascinating Properties of Metamaterials
Andrea Alù, University of Texas at Austin
Metamaterials and plasmonics offer unprecedented opportunities to tailor and enhance the interaction of waves with materials. In my introductory talk, I discuss the recent research progress in electromagnetics, nano-optics and acoustics, showing how suitably tailored meta-atoms and suitable arrangements of them forming advanced artificial materials open exciting venues to manipulate and control waves in unprecedented ways. I will discuss our most recent theoretical and experimental results, including nanostructures and metasurfaces to control wave propagation, scattering, and radiation, large nonreciprocal responses without magnetic bias, active meta-atoms and metasurfaces. Physical insights into these exotic phenomena, new devices based on these concepts, and their impact on technology will be discussed during the talk.
