Designer Matter: Meta-Material Interactions with Light and Sound
May 16, 2019 @ 12:00 pm
Dear Faculty and Students,
The Physics Department and Center for Theoretical Physics will conduct a seminar Thursday May 16 at 12:00 pm in Namm Room 823. Faculty and students are welcome. Light refreshments will be served.
Metamaterials are artificial materials with properties well beyond what offered by nature, providing unprecedented opportunities to tailor and enhance the interaction between waves with materials. In this talk, I discuss our recent research activity in electromagnetics, nano-optics and acoustics, showing how suitably tailored meta-atoms and arrangements of them open exciting venues to manipulate and control waves in unprecedented ways. I will discuss our recent theoretical and experimental results, including metamaterials for scattering suppression, metasurfaces to control wave propagation and radiation, large nonreciprocity without magnetic bias, giant nonlinearities in properly tailored metamaterials and metasurfaces, and active metamaterials. Physical insights into these exotic phenomena, new devices based on these concepts, and their impact on technology will be discussed during the talk.
