The sun's ascent above Earth's horizon is observed from the International Space Station, marking the approaching peak of ...

In this paper, we design a 38 GHz orbital angular momentum (OAM) antenna consisting of a horn antenna, a spiral phase plate (SPP), and a biconvex lens. The results show that this antenna design scheme ...

Mohawk Momentum Roadshow 2026 will make stops in the following cities: Atlanta: January 6-7, The Hotel at Avalon Dallas: January 7-8, Embassy Suites by Hilton Washington, D.C.: January 14-15, MGM ...

If you have thought that the Earth is close to the sun in the summertime and that is why it is hotter this time of year, you ...

Researchers take into consideration data collected by various satellites and spot fast solar winds changing the direction of ...

You might have seen the claim online, and it’s at least partially right, but it's not the only other number of days Earth has had.

With the continuous growth of network traffic, optical wireless communication (OWC) technology based on orbital angular momentum (OAM) can meet the needs of large-capacity modern communication and is ...

Learn how a new discovery of a giant planet can help scientists refine their theories of how planets form.

This work presents a method of structured light ranging that utilizes a relative phase modulation between two orthogonal beams. Application of a linear frequency modulated (LFM) signal in the relative ...

In this communication, an orbital angular momentum (OAM) mode-reconfigurable antenna based on a uniform circular array (UCA) is presented. To realize multiple switchable operating states while ...

Many spacecraft using more than 3 reaction wheels for both redundancy and extra maneuverability capabilities. Actuators configuration plays an effective role in the performance of the attitude control ...
