Briefs: Connectivity
A research team led by Rice University’s Edward Knightly has uncovered an eavesdropping security vulnerability in high-frequency and high-speed wireless backhaul links, widely employed in critical applications such as 5G wireless cell phone signals and low-latency financial trading on Wall Street. Read on to learn more.
Briefs: Photonics/Optics
In a paper published in the journal Nature Nanotechnology, a team of Caltech engineers reports building a metasurface patterned with miniscule tunable antennas capable of reflecting an incoming beam of optical light to create many sidebands, or channels, of different optical frequencies. Read on to learn more.
Briefs: Information Technology
Researchers have developed a new method for predicting what data wireless computing users will need before they need it, making wireless networks faster and more reliable. The new method makes use of a technique called a “digital twin,” which effectively clones the network it is supporting. Read on to learn more.
Briefs: Data Acquisition
Researchers have achieved data rates as high as 424Gbit/s across a 53-km turbulent free-space optical link using plasmonic modulators — devices that uses special light waves called surface plasmon polaritons to control and change optical signals. The new research lays the groundwork for high-speed optical communication links that transmit data over open air or space. Read on to learn more.
Briefs: RF & Microwave Electronics
With a goal to revolutionize cellular communications, Penn engineers have developed an adjustable filter that can successfully prevent interference, even in higher-frequency bands of the electromagnetic spectrum. Read on to learn more about the matter.
Briefs: Connectivity
