Metasurfaces: Near‐Field Characterization of Higher‐Order Topological Photonic States at Optical Frequencies (Adv. Mater. 18/2021)
Source abstract
Abstract
In article number 2004376 Andrea Alù, Alexander B. Khanikaev, and co-workers apply a near-field technique to investigate a higher-order topological photonic metasurface. They show that the near-field profiles reveal the topological nature of the optical modes (depicted as a torus). Topology manifests in the displacement of the Wannier center, giving rise to the topological dipole polarization and emergence of the topological boundary states observed in the optical near-field.
