In Situ Embedded FeSiB Nanocrystals in Amorphous Matrix With MOF‐Derived Porous Carbon for Enhanced Electromagnetic Wave Absorption

Rare Metals, Volume 45, Issue 6, June 2026.
ABSTRACT Because magnetic permeability is an intrinsic property of materials, achieving the regulation of magnetic loss is one of the challenges for electromagnetic wave absorption materials. This paper focuses on the research idea of in situ growth of dispersed nanocrystalline FeSiB in an amorphous FeSiB matrix to regulate magnetic properties.

Rock Physics of the Critical Zone: Models, Inversion, and Interpretation

Reviews of Geophysics, Volume 64, Issue 2, June 2026.
Abstract Rock physics models link geophysical measurements with subsurface petrophysical properties, such as porosity, mineral composition, and fluid saturation. While originally developed for hydrocarbon exploration, these models are increasingly applied in the near surface for quantitative interpretation of geophysical data.

Neural Network–Assisted Metasurface Retroreflector With Wide‐Angle Adaptivity

Electron, Volume 4, Issue 2, May 2026.
This work proposes a wide‐angle, multi‐polarization, self‐sensing, and self‐adaptive intelligent metasurface retroreflector, with a planar profile and ultrathin thickness. By integrating a pre‐trained artificial neural network (ANN), the metasurface retroreflector can recognize the incident angle and promptly adapt to changes in the incoming wave.

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 ...

Intelligent materials for on‐demand electromagnetic absorption

InfoMat, Volume 8, Issue 5, May 2026.
This review introduces an innovative “stimulus‐state‐property” paradigm, facilitating a fundamental transition from static to dynamically intelligent electromagnetic wave absorption (EMWA). The key advancement lies in the synergistic integration of external fields with structurally engineered metamaterials and tunable components.

From Molecular Motion to Macroscopic Function: Tailoring Tetraarylethylene Supramolecular Architectures for Aggregation‐Induced Emission and Wave Absorption

Rare Metals, Volume 45, Issue 5, May 2026.
ABSTRACT Integrating light emission and electromagnetic wave (EMW) absorption into a single material opens up possibilities for multienvironmental applications. Herein, we propose a novel “molecular engineering‐pyrolysis conversion” strategy to construct a bifunctional system with tunable photoluminescence and efficient EMW absorption performance.

Analysis and Reduction on in-Band RCS of Fabry-Perot Antennas

IEEE Access, 2020
In this article, a method is proposed to reduce the in-band radar cross section (RCS) of the high-gain Fabry-Perot antenna (FPA) based on the cancellation between the antenna mode RCS (AM-RCS) and structural mode RCS (SM-RCS).
