Multi‐LiDAR Observations of Coastal Atmospheric Duct Evolution in Hampton Roads
Abstract To better understand the influence of atmospheric ducts on radio frequency (RF) operations, continuous high‐resolution observations of temperature and water vapor are essential. Hampton University's (HU) 48‐inch Raman‐Mie LiDAR provides such measurements through rotational and vibrational Raman techniques, enabling detailed monitoring of ...

Traditional metasurfaces suffer from the drawbacks of pure microwave absorption and low IR emissivity stealth, namely failing to match complex ambient backgrounds with varying IR emissivity and generating excess heat accumulation (enhanced IR thermal radiation).

Nonreciprocal Electro‐Optic Intermodal Scattering With Momentum Engineered RF Waves
We demonstrate highly selective nonreciprocal intermodal scattering in thin‐film lithium niobate using slow‐wave RF transmission lines. This electro‐optic momentum engineering approach enables magnet‐free nonreciprocal devices with a single RF input. ABSTRACT Spatiotemporal modulation approaches have been often employed as alternatives for producing ...

Exploring Pb‐Chelation Chemistry in the Crystallization Dynamics of Halide Perovskites
A mechanism of how Pb‐chelation chemistry governs coordination geometry and initial nucleation behavior at the precursor level of halide perovskite, by regulating the deprotonation state of a chelating additive, is elucidated. This allows for innovative reaction‐system design principles that promote coherent growth while suppressing defect formation in
