Abstract: A leaky-wave antenna (LWA) array with high resolution beam scanning capability in two dimensions (2D) is presented in this paper. The antenna array is fed by a substrate integrated waveguide ...

Researchers have shown that consumer-grade 3D printers and low-cost materials can be used to produce multi-element optical components that enable super-resolution imaging, with each lens costing less ...

Scientists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory and collaborators have developed a new type of lidar—a laser-based remote-sensing instrument—that can observe cloud ...

Abstract: This article proposes a parallel programming and emitting (PPE) driving scheme for high-resolution active-matrix micro-LED (AM-$\mu $ LED) displays. The PPE scheme incorporates a 1 T-1 C ...

NASA will release new high-res images of interstellar comet 3I/ATLAS on Nov. 19, 2025. The comet, which originated outside our solar system, was first spotted in July and is only the third such object ...

Imagine trying to spot an object just 30 centimeters wide from hundreds of kilometers above Earth. Years ago, I remember when “satellite view” meant blurry green blobs on a screen. Now, we can see ...
