Dispersion‐Engineered Broadband Transparent Meta‐Cloak
Nanophotonics, Volume 15, Issue 9, 13 May 2026.Achieving broadband performance remains a critical challenge in engineering physics. Here, theoretical derivation shows that the core phase compensation conditions for broadband transparent cloaking exhibit dispersive characteristics. A novel broadband transparent cloaking paradigm via dispersion engineering is proposed, and a meta‐cloak that realizes ...

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.

Extending Loffeld's bistatic formula for the general bistatic SAR configuration
IET Radar, Sonar & Navigation, 2010 This study derives an accurate bistatic point target reference spectrum based on a zeroth-order polynomial model. The spectrum contains only two hyperbolic square root terms that are very analogous in form to the analytical monostatic spectrum. The new formulation can be considered as an improvement of the Loffeld's bistatic formula (LBF) and allows it

Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT This study employed a FeCoCrNiAl high entropy alloy matrix to regulate the nucleation and growth of SnS2 through solvent polarity, viscosity, and sulfur source release rates. Three distinct nanostructures including nanoribbons, nanoflowers, and nanosheets were synthesized and integrated onto a silicone rubber substrate.

Characterization of Mass Wasting Events on Lunar Maria Using Mini‐RF Radar Observations
Journal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.Abstract Evidence of mass wasting has been observed on the Moon since at least the Apollo era. Surface features indicative of mass wasting processes are traditionally characterized geomorphologically using visible images. In this study, we aim to better understand mass wasting features via their radar properties, which can provide insights into the ...
