Viktor Podolskiy, professor, physics and applied physics, UMass Lowell, will give a talk, “Beyond Materials: Using Electromagnetic Composites to understand and control light-matter interactions.”
Date: Wednesday, March 26
Time: 4 – 5 p.m.
Location: Olsen Hall 503
Abstract
Optics and photonics are central to many aspects of our lives. Refraction, emission and absorption of light within materials govern imaging, sensing, lighting and communications. However, many of these applications are often limited by properties of homogeneous materials. Composite-based metamaterials, whose electromagnetic response is driven not only by the composition but also by the arrangement of their components, offer new avenues to mold light. The talk will discuss advances in hyperbolic metamaterials in the quest to bend the laws or reflection and refraction, to avoid the onset of diffraction limit and to manipulate light at deep subwavelength scales.

Professor Viktor Podolskiy earned his B.S. degree in applied mathematics and physics from Moscow Institute for Physics and Technology, followed by M.S. in computer science and Ph.D. physics from New Mexico State University, and postdoc in electrical engineering at Princeton. Podolskiy is currently a professor and a graduate coordinator at the Department of Physics and Applied Physics, UMass Lowell. Podolskiy’s research is focused on theory and modeling of optical properties of nano- and micro-structured composites, metamaterials and plasmonic systems. He has presented over 30 invited talks and co-authored over 100 peer-reviewed publications, over 80 conference proceedings, and three U.S. patents. Podolskiy is a Fellow of Optica and APS.
