Structure–Property Relationship‐Guided Mechanisms for Electromagnetic Wave Absorption, Triboelectric Generation, and Negative Permittivity in Magnetic Metacomposites

Rare Metals, Volume 45, Issue 7, July 2026.
ABSTRACT The composition and structural characteristics of metacomposites are crucial for tuning their negative electromagnetic parameters; however, the lack of a clear structure–property relationship severely limits their application in dielectric and magnetic fields.

Heterointerfaces and Sulfur Vacancies in MXene/MoS2@C for Boosted Ultra‐Broadband Electromagnetic Wave Absorption and Infrared Stealth Response

Rare Metals, Volume 45, Issue 7, July 2026.
ABSTRACT Ti3C2Tx MXene shows significant potential in the field of electromagnetic wave absorption; however, the wave absorption performance was hindered due to the impedance mismatch, which was caused by its inherent high dielectric constant. In this work, Ti3C2Tx MXene co‐assembled with molybdenum disulfide nanosheets and carbon coating layers (MXene/

Large Cation‐Induced Lattice Distortion in Carbon‐Based High‐Entropy Oxides: Spin‐State Engineering and Broadband Microwave Absorption

Rare Metals, Volume 45, Issue 7, July 2026.
ABSTRACT High‐entropy oxides (HEOs) are promising for microwave absorption but suffer from a trade‐off between impedance matching and attenuation, often requiring high filling ratios (> 50 wt%). Herein, we propose a “lattice‐spin” dual‐regulation strategy by introducing giant‐radius Bi into a single‐phase HEO solid solution.

AIMP-Based Power Allocation for Radar Network Tracking Under Countermeasures Environment

Sensors
For radar system tracking, a higher radar echo signal to interference and noise ratio (SINR) implies a higher tracking accuracy. However, in a countermeasures environment, increasing the transmit power of a radar may not lead to a higher SINR due to ...

Infrared‐Microwave Compatible Stealth Transparent Metasurface With Digital Camouflage and Hybrid Absorption‐Scattering

Nanophotonics, Volume 15, Issue 12, 25 June 2026.
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).
