Gennady Shvets (UT Austin)
"Science and applications of infrared metamaterials: from thermo-photovoltaics to graphene-integrated plasmonic metasurfaces"
- Date: Monday, March 16, 2015
- Time: 3:00pm - 4:00pm
- Location: Smalley-Curl Room, Space Science 301A
- Wine & Cheese Reception after the talk
In this talk I will discuss novel directions in STPV that take advantage of plasmonic metamaterials. I will also discuss the prospects for turning metasurfaces into an actively-tunable platform for ultra-fast light manipulation. The rapid tunability is accomplished by integrating plasmonic metasurfaces with single-layer graphene.

Gennady Shvets is a Professor of Physics at The University of Texas at Austin. He received his PhD in Physics from MIT in 1995. He has been on the Physics faculty at the University of Texas at Austin since 2004. Previously he has held research positions at the Princeton Plasma Physics Laboratory and the Fermi National Accelerator Laboratory, and was on the faculty of the Illinois Institute of Technology. His research interests include nanophotonics, optical and microwave metamaterials and their applications (including bio-sensing, optoelectronic devices, and vacuum electronics), and plasma physics. He is the author or coauthor of more than 160 papers in refereed journals, including Science, Nature Physics, Nature Materials, Nature Photonics, Physical Review Letters, and Nano Letters. Dr. Shvets was a Department of Energy Postdoctoral Fellow in 1995-96. He was a recipient of the Presidential Early Career Award for Scientists and Engineers in 2000. He is a Fellow of the American Physical Society (APS) and Optical Society of America (OSA). His research is currently supported by various government agencies, including National Institute of Health, Department of Energy, National Science Foundation, Air Force Office of Scientific Research, and Office of Naval Research.
Professor Shvets is one of the pioneers in the emerging field of plasmonic metamaterials, especially in the infrared part of the spectrum. He and his colleagues were the first to experimentally implementing the concept of the Infrared Perfect Lens based on polaritonic materials (SiC), and the first to experimentally investigate optical properties of the so-called hyperbolic metamaterials that enable the propagation of sub-diffraction light waves. His group’s theoretical research addressed some of the most basic questions in metamaterials, including bi-anisotropy, homogenization, and Fano resonances. His most recent work deals with the applications of metamaterials and plasmonics to infrared light harvesting, thermal signature camouflage, solar thermo-photovoltaics, biosensing and molecular fingerprinting of proteins and cells using metamaterial arrays, nanoscale lasers/”spasers”, optical imaging with sub-diffraction resolution using nanoparticle labels, photonic topological insulators, graphene-based metamaterials, and electron beam-driven metamaterials. He is particularly interested in the integration of metamaterials and metasurfaces with various applications-specific platforms such as microfluidics, and in developing metamaterials-inspired devices that utilize non-traditional active, nonlinear, and low-loss materials such as graphene, silicon, and silicon carbide. Multiphysics modeling of electronic and optical behavior of such materials upon integration with plasmonic metamaterials using high-performance computing is another exciting challenge that his group is presently pursuing.
