Satellites Capture Record-Breaking 20-Metre Waves Crossing Entire Oceans ESA satellites recorded 20-meter ocean waves from Storm Eddie, the largest ever seen from space. These massive swells travelled ...

During recent storms, satellites recorded ocean waves averaging nearly 20 meters high—as tall as the Arc de Triomphe in Paris and the largest ever measured from space. Moreover, satellite data now ...

The long-wire dipole antenna is effective for low-frequency systems. Adding LC traps makes a single-band dipole antenna into a multiband unit. The historically significant long-wire dipole antenna may ...

Abstract: In this paper, we consider integrated sensing and communication (ISAC) enabled by an unmanned aerial vehicle (UAV) hovering at a fixed position in the air. Unlike previous works, the UAV is ...
