Reconfigurable Terahertz Multi‐Harmonic Dual‐Combs
Nanophotonics, Volume 15, Issue 17, 11 September 2026.Terahertz dual‐comb spectroscopy requires precise control of repetition frequencies. A reconfigurable dual‐comb system is realized on a single self‐detected quantum cascade laser platform, where harmonic order serves as a new tuning parameter. Switching among fundamental and harmonic states enables flexible multi‐heterodyne down‐conversion without ...

Metasurface‐Enabled Active‐Like Passive Radar
Advanced Science, Volume 13, Issue 44, 7 August 2026.A programmable space‐time‐coding metasurface embeds distinct spatiotemporal tags into ambient wireless signals, allowing passive radar to operate in an active‐like manner. By enabling code‐correlated reconstruction under interference, the approach supports robust real‐time UAV tracking in complex environments and points to intelligent, low‐power ...
