The landmark first detection, from two black holes colliding, was followed in 2017 by the first joint gravitational-wave and electromagnetic observation of a neutron-stars merger and subsequent ...

“The principle involves utilizing ultra-wideband, radially polarized, conical coaxial horn antennas to create a rotating electromagnetic wave structure,” the scientists said in a press statement.

In this study, high-frequency measurements of tides, waves, and currents were made using acoustic, electromagnetic, and pressure instruments over a 28-d period on the fore-reef and reef flat of a ...

The conical coaxial horn antenna generates an electromagnetic field in free space that rotates around the propagation direction of the wave structure. The researchers experimentally mapped the ...

Here's what we know so far. What happened across these two waves of attacks? On Tuesday, pagers used by hundreds of Hezbollah members exploded almost simultaneously in parts of Lebanon as well as ...

Just a day after hundreds of Hezbollah members' pagers exploded, Lebanon experienced another wave of electronic device detonations on Wednesday. These attacks, believed to be orchestrated by ...

BEIRUT — Walkie-talkies and solar equipment exploded in Beirut and other parts of Lebanon on Wednesday in an apparent second wave of attacks targeting devices a day after pagers used by ...

We found that the shoaling wave induces two distinct instabilities at different phases of the shoaling process, and that both can induce three-dimensional structure in an initially two-dimensional ...

In this article you will find specifically for Class 12 Physics Chapter 7 Electromagnetic Waves, the CBSE Board has given the practice question paper for students to understand and up skill there ...

Bandwidth spans 1.3GHz to at least 10GHz. “The principle involves utilising ultra-wideband, radially polarised, conical coaxial horn antennas to create a rotating electromagnetic wave structure,” ...

Scientists have discovered that ocean waves may become far more extreme and complex than previously imagined. The new study, published in Nature today, reveals that under specific conditions ...

The tech giant is launching a new suite of updates – that the company is calling ‘Wave 2’ – to its Copilot AI-powered digital assistant for Windows. As well as tweaks that will integrate ...
