Tunable High‐Performance Metamaterial Filters Based on Novel SRR Architectures

Advanced Science, EarlyView.
Based on two novel SRR configurations and two independent SRR integration approaches, four tunable bandpass metamaterial filters were fabricated with an ultra‐thin ceramic substrate. Among them, SM‐2 achieves over 97% electromagnetic wave transmittance, with a minimal 1.15% deviation in its resonant frequency prediction, making them promising ...

Unidirectional Evaporation‐Induced Tunable and Continuous Gradient Composite Structure for Absorption‐Dominant Electromagnetic Interference Shielding

Advanced Science, EarlyView.
A continuous conductivity gradient is formed in a porous MXene/melamine foam via directional evaporation, thereby improving impedance matching and enhancing electromagnetic attenuation. The resulting monolithic composite delivers absorption‐dominant EMI shielding with ultralow reflection, offering a simple route toward lightweight EMI shielding ...

Ferromagnetic Resonance Response of bcc Fe60V40 Layers Generated from Short‐Range Ordered Precursors

Advanced Electronic Materials, EarlyView.
ABSTRACT Layers of body‐centered cubic (bcc) Fe60V40 are generated in short‐range ordered (SRO) Fe60V40 precursors through atomic displacements caused by the irradiation of light noble gas ions. The structural change leads to the onset of ferromagnetism confined to the bcc layers. Here, the variation of ferromagnetic resonance response as a function of
