Sparse‐Aperture Quasi‐Achromatic Spintronic Terahertz Emitter Enabled by Binary‐Phase Metasurface and Multi‐Spectral Intensity Optimization

open access: yesNanophotonics, Volume 15, Issue 19, 13 October 2026.
We propose a sparse‐aperture shared‐aperture design with multispectral intensity optimization, enabling a Pt/W binary‐phase metasurface directly integrated with a spintronic emitter. The device achieves quasi‐achromatic focusing across 1.0–1.5 THz, with intensity fluctuation below 33% and edge preservation above 0.68.
