The film discusses the evolution and potential of using light waves, particularly coherent light, for communication. It ...

The use of terahertz waves, which have shorter wavelengths and higher frequencies than radio waves, could enable faster data transmission, more precise medical imaging, and higher-resolution radar.

You can't see the electromagnetic spectrum, but its connections are crucial to our defense systems.

China's tightening grip on radio frequencies critical for advanced technologies - from 5G networks to AI-driven weapons - ...

Bryan Clark testifies before the Senate Committee on Commerce, Science, and Transportation.

Researchers at the University of Twente have solved a long-standing problem: trapping optically-generated sound waves in a ...

The sky is awash with radio-frequency interference (RFI), but thanks to two astronomers who tracked down a stray TV broadcast reflected off a passing airplane, there may be a new way to wipe out some ...

A low-power system from MIT uses radio frequency waves takes a step toward autonomous, indoor drone navigation ...

An American Astronomy team at Brown University found themselves in a mystery when an Australian telescope recorded some ...

MIT researchers developed a system that enables a drone to determine its position in 6D space in indoor, dark, or low-visibility environments using radio frequency waves.  They drone has 2 radars; the ...

Through hundreds of test flights, the MIT team found that MiFly consistently provided location accuracy within 7 centimeters.

In the future, autonomous drones could be used to shuttle inventory between large warehouses. A drone might fly into a semi-dark structure the size of several football fields, zipping along hundreds ...
