Plasmonics on Two-Dimensional Materials

Dionisios Margetis, Professor, University of Maryland

4:00 pm to 5:00 pm | Pierce Hall, 209

Abstract:

The advent of two-dimensional materials with a wide range of optical and electronic

properties offers the promise of exceptional efficiency in light-matter interaction.

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 and curvature as well as the formation of periodic structures, can affect SPP dispersion; and discuss implications of these results for applications.
