New software from Tenna Systems maps out the interference landscape by assembling telemetry data from existing radios, and allows jammers to be avoided — or targeted.

Abstract: The frequency dithering techniques (FDT) to attenuate electromagnetic interference (EMI) are widely researched in the literature. However, the existing FDTs cannot be applied to resonant ...

Turn coaxial cable into a DIY TV antenna in minutes. Make a few cuts, bend a wire, then run a channel scan to pick up free over-the-air broadcasts.

The breakthrough, detailed in Nature Photonics, centers on a fundamental problem facing 6G: how to efficiently transmit and receive data at terahertz frequencies. These frequencies, which ...

Using ideas borrowed from topological photonics, researchers in Singapore, France and the US have designed a compact antenna ...

Abstract: The distance of direct phone-to-satellite communication is significantly greater than that of cellular communication. The long distance leads to a high path loss, where a high-gain mobile ...

Vascular cognitive impairment (VCI), a cognitive disorder arising from cerebrovascular pathology, currently lacks effective targeted therapies. Dysfunction of the blood–brain barrier (BBB) represents ...

ESA fired a ‘non-explosive actuator’ in stuck bracket of the ESA JUICE spacecraft's RIME antenna to jar in loose. Mission controllers have been trouble shooting the antenna deployment for 3 weeks.
