To tackle this challenge, this study presents a design and optimization approach for a miniature UAV antenna. This antenna achieves significant performance improvements by optimizing the magnetic ...

Earth's magnetic field dramatically flipped a little more than 40,000 years ago. We can now experience this upheaval as an unnerving clatter interpreted from information collected by the European ...

The solution combines measurements of the antenna characteristics with simulation of the electromagnetic (EM) wave propagation to optimize the antennas’ design and their position to ensure for example ...

Summary: Scientists have developed magnetic nanodiscs that enable targeted brain stimulation without invasive implants or genetic modifications. The tiny discs, activated by an external magnetic field ...

A new publication from Opto-Electronic Sciences; DOI 10.29026/oes.2024.240014, discusses how AI and physics unite for meta-antennas design. Ka-band metasurface antennas, with their low-cost, ...

Ka-band metasurface antennas, with their low-cost, low-profile design and superior beam-steering capabilities, show significant potential in the field of satellite communications. However, the ...

Abstract: A compact broadband loop complementary source antenna with four switchable tilted beams is proposed in this paper. The antenna is constructed by adding vertical quarter wavelength shorting ...

Approximately 41,000 years ago, Earth's magnetic field briefly reversed during what is known as the Laschamp event. During this time, Earth's magnetic field weakened significantly—dropping to a ...

When Loop offered me the chance to try its new Dream earbuds, the first from the brand specifically made for sleep, I leapt at the opportunity to potentially get a good night’s rest. Having ...

The feature is known as Loop, and one developer who spotted the reference said that it might be similar to the Communities feature on X, or subreddits … Alessandro Paluzzi first found the feature.
