Exotic Light-Matter Interactions in Metamaterials

Andrea Alu (CUNY Graduate Center)

Location:  Hill 705
Date & time: Friday, 22 November 2019 at 4:00PM - 5:00PM

Abstract:  Metamaterials are artificial materials with properties that go well beyond what offered by nature, providing unprecedented opportunities to tailor and enhance the control of waves. In this talk, I discuss our recent activity in electromagnetics and acoustics, showing how suitably tailored meta-atoms and their arrangements open exciting venues for enhanced wave-matter interactions. I will discuss unusual scattering, absorption and waveguiding responses, from cloaking and scattering suppression, to nonreciprocity and topological phenomena, enhanced nonlinear effects at subwavelength scales, and bound states in the continuum. Physical insights into the underlying phenomena and new devices based on these concepts will be presented.
