Advanced Intelligent Systems, EarlyView.This work develops a CGAN‐based metasurface inverse design method. It adopts an integrated workflow of pixel‐based graphical modeling, simulation, and GAF transform for automatic, batch metasurface dataset construction. With a U‐Net architecture, the CGAN generates high‐resolution, high‐fidelity metasurface structures. EIT verification achieves over 90%

The Interplay of Crystal‐Field Transitions and Exchange Spin Dynamics in a Ferrimagnet
Advanced Physics Research, EarlyView.Temperature‐dependent THz spectroscopy reveals strong hybridization between Yb3+ CEF excitations and Yb–Fe exchange dynamics in Gd3/2Yb1/2BiFe5O12. Near the magnetization compensation temperature, spectral weight is redistributed between the coupled modes, while the Yb–Fe exchange mode exhibits an anomalous redshift upon cooling due to CEF‐mediated ...

Direction of Arrival Estimation in Terahertz Communications using Convolutional Neural Networks
We demonstrate an approach to accurately estimating the Direction of Arrival (DoA) in terahertz communications using Convolutional Neural Networks (CNNs). Quasi-random patterns are generated with a frequency-diverse antenna which is deliberately designed

Chemistry – A European Journal, EarlyView.Two families of bTurea‐derived biradicals, bcTmols and bcTCOOKs, were prepared as polarizing agents for dynamic nuclear polarization (DNP)‐enhanced NMR through short and efficient synthetic routes. The best‐performing biradical, bcTCOOK‐M2, containing two methyl groups on the urea bridge, provided signal enhancements of up to ∼220 at 14.1 T and 100 K ...

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.Our computational model of the optical absorption from multiwalled carbon nanotubes suggests the optical absorption depends strongly on the in‐plane electrical conductivity, and weakly on the through‐plane conductivity. Such strong absorption enables solar‐to‐thermal conversion for heat scavenging in cold climates and radiative cooling in hot climates,
