Design, Simulation, and Fabrication of High‐Performance Metamaterial Absorber for EMI Mitigation and THz NDT/Imaging Applications: A Shape‐Preserved GHz‐to‐THz Transition Approach

Advanced Theory and Simulations, EarlyView.
A novel metamaterial absorber is designed, simulated, and validated for both 5G mmWave and THz applications, achieving >95.8% and 90% absorption, respectively. Its polarization‐insensitive, scalable design enables applications in THz NDT, imaging, and EMI shielding.

Oxygen Vacancy Formation at Metal‒TiO₂ Interface Yielding Enhanced Photocatalytic Hydrogen Generation

Advanced Science, EarlyView.
In this work, the oxygen vacancy formation is reported at the Au‐TiO2 interface in strong metal‐support interaction (SMSI) photocatalyst. The oxygen vacancies faciliate electron transfer and favor the adsorption of water and methanol at photocatalyst surface, thus enhancing the kinetic of photocatalytic hydrogen generation. The SMSI concept is extended

VOx‐Based Non‐Volatile Radio‐Frequency Switches for Reconfigurable Filter

Advanced Science, EarlyView.
Vanadium oxide‐based memristor devices achieve high performance for next‐generation non‐volatile memory and RF switches. These devices demonstrate a cutoff frequency of ≈4.5 THz, low insertion loss (<0.46 dB), and high isolation (>20 dB) from 0.1 to 20 GHz with stable operation extended to 67 GHz.

Generalized Phase Tailoring of Arbitrary Orthogonal Polarizations in Meta‐Structure with High‐Order Geometric Symmetry

Advanced Science, EarlyView.
A generalized methodology is proposed for Cm (m ≥ 3) meta‐structures to achieve independent phase control of arbitrary orthogonal polarizations. By integrating orientation tuning with structural tailoring, this approach extends spin‐based designs to polarization‐diverse wavefront engineering, enabling multi‐functional and high‐efficiency meta‐devices ...
