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.
