New chip poised to enable hand-held microwave imaging

Researchers have developed a new microwave imager chip that could one day enable low-cost handheld microwave imagers, or cameras. Because microwaves can travel through certain opaque objects, the new imagers could be useful ...

Scientists develop filter to suppress radio interference

Researchers from Siberian Federal University and Kirensky Institute of Physics have proposed a new design for a multimode stripline resonator. The use of such resonators allows scientists to create miniature band-pass filters ...

Cassini explores ring-like formations around Titan's lakes

Using observations from the international Cassini spacecraft, scientists have explored the ring-like mounds that wrap around some of the pools found at the poles of Saturn's largest moon, Titan. The study reveals more about ...

Virtual tests for autonomous driving systems

Sensors in autonomous vehicles have to be extremely reliable, since in the future motorists will no longer constantly monitor traffic while underway. In the past these sensors were subjected to arduous road tests. The new ...

Why Tehran is sinking dangerously

Iran has a water problem. The reserves in many groundwater basins there have been severely depleted. For the last 40 years, the country has invested a lot in the agricultural sector, and has been striving to be independent ...

Can radar replace stethoscopes?

Along with a white coat, a stethoscope is the hallmark of doctors everywhere. Stethoscopes are used to diagnose the noises produced by the heart and lungs. Used in the conventional way, vibrations from the surface of the ...

Optically tunable microwave antennas for 5G applications

Multiband tunable antennas are a critical part of many communication and radar systems. New research by engineers at the University of Bristol has shown significant advances in antennas by using optically induced plasmas ...
