First, the payload requirements and problems faced by traditional multi-beam antenna are described. The user beam of the VHTS payload system mainly uses Ka-band multi-beam antenna for a large range of ...

A new method in electron microscopy enables sub-20-picometer targeting of individual atoms without prior exposure, opening the door to atom-specific analysis and control. (Nanowerk Spotlight) ...

New ion beam fabrication uses low cost materials to form vertical nanomagnets whose nanostrip geometry boosts sensitivity to magnetic fields and current pulses. (Nanowerk News) Researchers at HZDR ...

WASHINGTON — Researchers have developed a new method for flexibly creating various needle-shaped laser beams. These long, narrow beams can be used to improve optical coherence tomography (OCT), a ...

Adaptive laser beam shaping with a deformable mirror enables efficient energy and material usage in laser welding and ...

People like to keep a safe distance from explosive substances, but in order to analyze them, close contact is usually inevitable. A new method has now been developed to detect chemicals inside a ...

Microscope images could be obtained much more quickly -- rather than one pixel at a time -- thanks to a new imaging method for neutral atomic beam microscopes. It could ultimately lead to engineers ...
