Zn(C2H4NO2)2(SO2CH3NH2)2 and Zn(C2H4NO2)2[SO2(NH2)2]: Regulation of Unique ZnO(C2H4NO2)2 Units by Polar Tetrahedrons for Balanced UV Nonlinear Optical Performance

Advanced Science, EarlyView.
The modulation of polar tetrahedra enabled the synthesis of an outstanding short‐wave UV NLO crystal, Zn(C2H4NO2)2[SO2(NH2)2], which achieves a rare balance of a large bandgap (5.93 eV), high birefringence (Δn = 0.126 at 546 nm), and strong SHG response (1.36 × KDP), especially achieving excellent phase‐matching throughout the full transparency range ...

Metasurface‐Enabled Active‐Like Passive Radar

Advanced Science, EarlyView.
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 ...
