Optical vortices—light beams carrying orbital angular momentum (OAM)—are characterized by helical wavefronts and phase ...
Abstract: An integrated antenna system covering 5G Sub-6 GHz and millimeter-wave bands is proposed, combining a spoof surface plasmon polariton (SSPP) antenna and two Vivaldi arrays. The integrated ...
A new analysis reveals what happens when very short or narrow electron beams encounter a particle. The research is published ...
Japan’s move on Bali forced ABDA into a rushed, multi-wave attack with cruisers, destroyers, and torpedo boats arriving piecemeal. Torpedoes missed, formations scattered, ships were hit and crippled, ...
From a surprising heat wave in California to blizzards burying parts of the Midwest and storms rolling over the East Coast, chaotic weather put more than half the nation's population in the path of ...
Add Yahoo as a preferred source to see more of our stories on Google. From a surprising heat wave in California to blizzards burying parts of the Midwest and storms rolling over the East Coast, ...
We revisit the theoretical modeling and simulation of a Gaussian stochastic gravitational wave background (SGWB) signal in a pulsar timing array (PTA). We show that the correlation between Fourier ...
Researchers from Southeast University in China have developed a compact, dual-band, dual-polarized, duplex (D³) phased array architecture that integrates four independent beamforming systems on a ...
SEA has been awarded a multi-million-pound contract to supply its advanced KraitArray undersea sensing technology to Liquid Robotics, a Boeing Company, for integration into the company’s Wave Glider ...
The year isn't over yet, but we've already seen record-breaking quantum computers, skyrocketing levels of investment, and demonstrations of real-world benefits. In all the hype about AI it can be easy ...
The energy in breaking waves is being put to new use generating electric power. In September, Eco Wave Power launched the first U.S. wave energy project at the Port of Los Angeles. It attaches ...
