On the minimum number of tracks for SAR tomography [PDF]
, 2008 The main drawback of SAR Tomography (SARTom) is the considerable number of tracks required to achieve the 3-dimensional (3D) representation of a viewed scene.

Advanced Materials Interfaces, EarlyView.This study develops a self‐cleaning solar evaporator based on MXene‐coated aramid nanofiber aerogels for efficient desalination under high‐salinity conditions. The cylindrical evaporator combines strong photothermal conversion, capillary water transport, and self‐rotation triggered by salt accumulation.

The Radiometric Measurement Quantity for SAR Images [PDF]
, 2013 A Synthetic Aperture Radar (SAR) system measures among other quantities the terrain radar reflectivity. After image calibration, the pixel intensities are commonly expressed in terms of radar cross sections (for point targets) or as backscatter ...

The Staggered SAR concept: Imaging a wide continuous swath with high resolution [PDF]
, 2013 Staggered SAR is an innovative synthetic aperture radar (SAR) concept, based on the continuous variation of the pulse repetition interval (PRI). This concept allows high-resolution imaging of a wide continuous swath without the need for a long antenna ...

Coherent Absorption Reveals Colors Hidden in a Grey Fabry–Pérot Cavity
Advanced Optical Materials, EarlyView.A dielectric thin film shows colors depending on its thickness; this effect can be used to encode information normally accessible through single‐beam spectroscopy. We developed a method to conceal this kind of information, based on coating the dielectric with a matched conductor, that suppresses the color‐bearing thin‐film resonances.

Nonlocomotory Robotic Strategies for Dynamic Rotation Control in Terrestrial Robots: A Review
Advanced Robotics Research, EarlyView.Terrestrial robots increasingly require rapid body rotation to maintain stability and agility in complex environments. This review shows nonlocomotory rotational control strategies that operate without ground contact, including reaction wheels, tails, bars, limbs, and thrusters.
