Laser prototype for space-based gravitational wave detector

Researchers have announced a prototype for a laser at the heart of the first space-based gravitational wave observatory, known as the Laser Interferometer Space Antenna (LISA) mission. The team's new laser nearly meets 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 ...

A view inside ESA's cavernous Hertz chamber for radio-frequency testing of satellites, which will be on show to the public during this Sunday's ESA Open Day in the Netherlands.

Many antennas, multiple benefits

A concept that balances large-scale installations of low-cost and low-power antennas to boost cellular coverage in difficult environments will also provide better connectivity to more users. Developed by A*STAR, this new ...
