The specific spatial size of the EMIC wave source region and the 3D aspect of how the propagation path is formed from space to ground are yet to be elucidated. The international collaborative ...

The TRANSMISSION of acoustic energy through a medium via a SOUND WAVE. See: SOUND ... Wiener and Keast, "Experimental Study of the Propagation of Sound Over Ground," Journal of the Acoustical Society ...

Ground wave radio propagation along the surface of the Earth. Courtesy of Electronics-Notes.com LowFER, as the name would suggest, contains the lowest frequency range of the three, falling between ...

At shortwave frequencies, distant propagation is much more common. Shortwaves travel via ground wave (short distance) and sky wave. However, parts of our atmosphere–particularly, the part about ...

Researchers have mathematically elucidated how the presence of crystals and gas bubbles in magma affects the propagation of seismic P-waves. A novel equation was derived to describe the travel of ...

To operate HAPS-based networks as communications infrastructure, the accurate calculation of radio wave propagation from the stratosphere to the ground in various environments is essential. The “HAPS ...

During the daytime, AM signals primarily propagate close to the ground (known as ground wave propagation) and follow the curves of the Earth. In the daylight hours, AM signals sent by radio ...

This supermagnonic propagation offers opportunities for even faster, smaller and more energy-efficient ways of data processing in future computers. The research will be published in Physical ...
