A Cross-Track Interferometric Synthetic Aperture 3D Passive Positioning Algorithm

Remote Sensing
High-precision, robust, and rapid three-dimensional (3D) passive positioning of the radiation source is critical for modern reconnaissance systems. While synthetic aperture technology has advanced 2D passive positioning performance, existing methods fail

Exciton‐Polaritons in Nanoscale Metal‐Organic Frameworks: A Platform for the Reversible Modulation of Strong Light‐Matter Coupling via the Chemical Environment

Advanced Functional Materials, EarlyView.
Strong exciton‐photon coupling is achieved by integrating porphyrin ligand‐based MOF nanoparticles in optical cavities, as evidenced by pronounced polariton branch anticrossing. The porous nature of the resonator enables precise, reversible tuning via vapor pressure, unlocking unprecedented chemical‐environment controlled dynamic polaritonic platforms ...

Multi‐Area Controllable Suppression Jamming Method Against SAR Based on Two‐Dimensional Phase Mismatch

IET Radar, Sonar & Navigation
In the imaging process of SAR, the secondary phase mismatch can cause image defocusing. In this paper, a suppression jamming method against SAR based on two‐dimensional (2D) phase mismatch is proposed through a designed jammer system.

Refining Constraints on the Origin of Lunar Irregular Mare Patches via Mini-RF and DFSAR Data Analysis

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Irregular mare patch (IMP) is one of the most enigmatic volcanic features in the lunar nearside maria. Their apparently fresh surface morphology and derived young model ages contradict the currently proposed thermal evolution history of the Moon.

Nano‐ and Micro‐Sized Solid Materials Used as Antiviral Agents

Advanced Functional Materials, EarlyView.
Due to the rise of viral infections in humans and possible viral outbreaks, the use of nano‐ or micro‐sized materials as antiviral agents is rapidly increasing. This review explores their antiviral properties against RNA and DNA viruses, either as a prevention or a treatment tool, by delving into their mechanisms of action and how to properly assess ...

MFE-STN: A Versatile Front-End Module for SAR Deception Jamming False Target Recognition

Remote Sensing
Advanced deception countermeasures now enable adversaries to inject false targets into synthetic-aperture-radar (SAR) imagery, generating electromagnetic signatures virtually indistinguishable from genuine targets, thus destroying the separability ...

Conductive Bonding and System Architectures for High‐Performance Flexible Electronics

Advanced Functional Materials, EarlyView.
This review outlines bonding technologies and structural design strategies that support high‐performance flexible and stretchable electronics. Bonding approaches such as surface‐activated bonding and anisotropic conductive films, together with system‐level architectures including buffer layers and island‐bridge structures, possess distinct mechanical ...
