Title: Plasmonics on Two-Dimensional Materials
Abstract: The advent of two-dimensional materials with a wide range of optical and electronic properties offers the promise of exceptional light-matter interactions. These systems may allow for the propagation of short-scale electromagnetic waves, called surface plasmon-polaritons (SPPs), which can defy the usual diffraction limit. In this talk, I will present recent advances in understanding how the material geometry, e.g., the presence of edges as well as the formation of periodic structures with 2D materials, can affect the subwavelength SPP dispersion; and discuss physical implications of these results.
Bio: Dionisios Margetis is a Professor of Mathematics and the Institute for Physical Science and Technology, jointly with the Center for Scientific Computation & Math. Modeling, at the University of Maryland, College Park. After receiving the Electrical Engineering Diploma from the National Technical University of Athens, Greece, he went on to Harvard for a PhD in Applied Physics. Then, he carried out postdoctoral work in applied physics and applied mathematics at Harvard and M.I.T. He joined the faculty at the University of Maryland in 2006. He has been a full Professor since 2012. He was a recipient of: an NSF Career Award; two Research and Scholarship Awards, and Dean’s Award for Excellence in Teaching at Maryland; and Dean’s Prize for Excellence in Graduate Education by M.I.T. His research focuses on plasmonics, epitaxial growth and quantum dynamics. He was a SIAM plenary speaker in mathematical aspects of materials science in 2018. In 2019-20, he is a Distinguished Ordway Lecturer and Visitor at the University of Minnesota.
