Researchers from Southeast University have developed a compact, dual-band, dual-polarized phased array for B5G/6G ...

Phased array antenna systems are at the cusp of ubiquity. We now see Multiple-Input Multiple-Output (MIMO) antenna systems on WiFi routers. Soon phased array weather radar systems will help to predict ...

The current network of weather radars in the United States was installed in the late 1980s and into the 1990s. There are nearly 160 weather radars in the network. The radars are the NEXRAD WSR-88D ...

A 4-element Vivaldi subarray PCB tile is designed for 6 GHz to 18 GHz 1-D phased array scanning. Grating lobe suppression techniques and defected ground structures are used to extend the capable ...

What are optical phased arrays? Optical phased arrays (OPAs) are devices that manipulate the cross-sectional shape and direction of optical beams in accordance with the principles of optical ...

In a recently published study in the journal EPSL neuroelectronics, researchers from The Pennsylvania State University and Washington University in St. Louis have introduced a modular 16-channel ...

Echodyne has developed a family of palm-sized metamaterial electronically-scanning array (MESA) radars for missions such as counter-unmanned aerial system (C-UAS), special event security, and UAS ...

Austenitic welds and welds that contain heterogenous weld materials are increasingly used in various industries. These welds can be used to manufacture components with enhanced or custom-engineered ...
