Abstract Scope |
Geometrical singularities in plasmonic nanoparticles may be designed to create localized edge modes and concentrated field enhancement in the proximity of the singularity. In such cases, scattering and absorption from the particle may be structurally tunable with high sensitivity to the local material properties, edge angles, and the polarization of the excitation field. In this work, we investigate extinction properties of a class of singular plasmonic nanoparticles in form of truncated half-cylinders. We analytically study the formation and properties of the edge modes, followed by numerical investigations on the tunability and sensitivity of the extinction properties of these particles. Finally, arrays of singular plasmonic nanoparticles (in form of metasurfaces) will be explored. |
