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: Robotics, Automation & Control
For the first time, researchers at The University of Texas at Austin’s Applied Research Laboratories and NASA’s Goddard Space Flight Center have formed a radio interferometer between a GPS antenna and receiver and a large radio telescope. Read on to learn more about the new technique.
Briefs: Software
To help improve the safety and security of AVs, researchers have devised a novel algorithm designed to mimic an attacking device. The algorithm lets researchers identify areas for improvement in autonomous vehicle security.
