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.

Metamaterial Antennas Enhance MRI of the Eye and Occipital Brain

Advanced Materials, EarlyView.
A radiofrequency antenna platform comprising planar and bend configurations is developed, incorporating structurally integrated epsilon‐negative metamaterial unit cells to enhance MRI. These antennas enable high‐resolution in vivo human MRI of the eye, orbit, and occipital brain. Comprehensive validation, including simulations, phantom experiments, SAR,

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.

A Real-Time MPSoC-Based Back Projection Accelerator for High-Accuracy Large-Size SAR Imaging Using Truncated Sinc Reconstruction and Mixed Precision Design

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
The back projection (BP) algorithm has become an important method for achieving high-resolution synthetic aperture radar imaging due to its model-free assumptions, high imaging accuracy, and strong trajectory adaptability. However, its high computational

n‐Type Polymer Radio Frequency Rectifiers Operating at 18.5 GHz

Advanced Materials, EarlyView.
Combining an n‐doped polymer semiconductor with wafer‐scale asymmetric planar electrodes featuring work function‐engineered contacts yields radio‐frequency diodes and rectifying circuits operating at up to 18.5 GHz. The devices combine scalable manufacturing with an operating frequency previously unattainable by large‐area organic electronics ...
