Researchers developed a low-cost, scalable terahertz amplifier that could be used to make antenna arrays that can steer and focus high-frequency terahertz waves, for applications like high-resolution ...

Safran Defense & Space, Inc. (Safran DSI), a world leader in testing and telemetry solutions, has secured an order from Bell Textron Inc., a Textron Inc. Company, to ...

Antennas receive and transmit electromagnetic waves, delivering information to our radios, televisions, cellphones and more.

In Maryland, Kent County High School's 90.5 WKHS(FM) used its newly minted K3ARS amateur radio station to work 40 stations on ...

Abstract: In this letter, a phase synthesis method for mechanical beam scanning based on the feed displacement technique (FDT) is proposed for reflectarray antennas. To verify the correctness of the ...

The US military has released footage of Marines in California fortifying the barrier on the border with Mexico, as the Trump administration continues steps to curb illegal immigration. The 'nerd ...

There may also be benefits to a system that’s theoretically able to scale power upward by adding additional HPM antennas. Furthermore, a disaggregated system with multiple beam-generators might ...

Weekend travelers must steer clear of the Capital Beltway Inner Loop along Tysons in Virginia these next few days, as the “Big Beam Weekend” road project comes underway. The Virginia ...

Abstract: This paper describes a new method for synthesis of a flat-top beam radiation pattern of three-element antenna arrays. Currently, this is the only method that: (1) gives a semi-analytical ...
