Image: Mesh reflector for shaped radio beams

This prototype 2.6-m diameter metal-mesh antenna reflector represents a big step forward for the European space sector: versions can be manufactured to reproduce any surface pattern that antenna designers wish, something ...

Laser beams reflected between Earth and moon boost science

Dozens of times over the last decade NASA scientists have launched laser beams at a reflector the size of a paperback novel about 240,000 miles (385,000 kilometers) away from Earth. They announced today, in collaboration ...

Engineer develops new reflector for radar measurements

Cornelius Senn, a measurement engineer in the Department of Civil, Environmental and Geomatic Engineering (D-BAUG), and his post-doctoral colleague Silvan Leinss have developed a new reflector for radar measurements. The ...

VTT brings reflectors up to date with sensors and LED lights

In collaboration with the Coreplast Laitila company, VTT Technical Research Centre of Finland has created a reflector that can be wirelessly controlled via a mobile phone application. This involves equipping a traditional ...

SMAP satellite extends 5-meter reflector boom

Like a cowboy at a rodeo, NASA's newest Earth-observing satellite, the Soil Moisture Active Passive (SMAP), has triumphantly raised its "arm" and unfurled a huge golden "lasso" (antenna) that it will soon spin up to rope ...

Acoustic levitation made simple

A team of researchers at the University of São Paulo in Brazil has developed a new levitation device that can hover a tiny object with more control than any instrument that has come before.
