Designer Matter—Fascinating Interactions of Light and Sound with Metamaterials
The Kavli Foundation is dedicated to advancing science for the benefit of humanity, promoting public understanding of scientific research and supporting scientists and their work.
Metamaterials are artificial materials with emerging physical properties that go well beyond their constituents and what is offered by nature, providing unprecedented opportunities to tailor and enhance the interaction between waves and matter. In this talk, I discuss our recent research activity in electromagnetics, nano-optics, acoustics and mechanics, showing how suitably tailored meta-atoms and their arrangements open exciting venues to manipulate and control waves in unprecedented ways. I will discuss our most recent theoretical and experimental results, including metamaterials for scattering suppression, nanostructures and metasurfaces to control wave propagation and radiation, large nonreciprocity without magnetism, giant nonlinearities in properly tailored metasurfaces, and parity-time symmetric meta-atoms and metasurfaces. Physical insights into the exotic phenomena behind the metamaterial response, new devices based on these concepts, and their impact on technology will be discussed during the talk.
