Absorption‐Dominant Electromagnetic Interference Shielding of Ti3C2Tx MXene‐Coated and Fe3O4‐Integrated TPMS Composites with Coupled Gradient Conductivity and Size‐Graded Structure

Advanced Science, EarlyView.
A functionally driven variable‐cell size and gradient‐conductive coated TPMS structure was developed. Accordingly, stepwise longitudinal gradient impedance was realized, achieving absorption‐dominant EMI shielding (absorptivity≈0.85) with an EMI SET of ≈ 59 dB, for 10 mm‐thick composites. Further increasing the thickness of composites to 20 mm achieved

Synthetic aperture radar images of ocean waves, theories of imaging physics and experimental tests [PDF]

, 1984
The physical mechanism for the synthetic Aperture Radar (SAR) imaging of ocean waves is investigated through the use of analytical models. The models are tested by comparison with data sets from the SEASAT mission and airborne SAR's.

Wearable Cooling Textiles of Thermal Conduction and Sweat Transfer for Personal Thermal Management

Advanced Science, EarlyView.
This study constructs a three‐dimensional thermal‐conductive pathway using biomass‐based fibers. The thermally conductive composite fibers were designed into Janus‐structured fabrics. The wearable cooling textile exhibits unidirectional moisture‐wicking properties (476% index), a high water evaporation rate (5209.92 g/m2/day), and effective skin ...

Array Radar Three-Dimensional Forward-Looking Imaging Algorithm Based on Two-Dimensional Super-Resolution

Sensors
Radar imaging is a technology that uses radar systems to generate target images. It transmits radio waves, receives the signal reflected back by the target, and realizes imaging by analyzing the target’s position, shape, and motion information. The three-
