"depending on incoming near-IR laser polarization, nonlinear programmable metasurface generates either electric-/ magnetic-mode vortex skyrmions (future: more modes) stable/ resistant to environmental noise/ physical obstacles even with limited bandwidth since topologically protected... high-capacity multiplexing: encodes data into the light's shape, adding new channels to same frequency... laser polarizations create different 3D shapes (skyrmions) carrying data via 6G+ safely through crowded areas"
