The ionosphere is the upper portion of Earth's atmosphere consisting of free electrons, which are influenced by solar winds and geomagnetic storms. Radio waves from satellites to Earth travel at ...

once we create the waves they propagate exactly the way Tesla conceived it through the earth ionosphere waveguide. Tesla proposed that it might be possible to modify the weather, by using radio ...

SOME years ago considerable discussion took place concerning the relation between the constitution of the ionosphere and its refractive index for radio waves. The question at issue was whether the ...

The ionosphere consists of several layers that reflect and refract radio waves, allowing high-frequency radio signals to travel long distances around the world. When solar flares ionize the D ...

The effects are mostly related to the propagation of radio waves via the ionosphere. In the 1700s, who would care? In the mid 20th century, though, lots of things relied on this property of high ...

The ISR has numerous projects to explore the phenomenology of the Earth's ionosphere, the region of the Earth's upper atmosphere that is dominated by ions and free electrons. Investigations include ...

When they propagate through a vacuum, they are radio waves propagating at the speed of light. However, when they move into the ionosphere, they turn into plasma (whistler) mode waves, and propagate at ...

As Earth's orbit becomes populated with more crafts and devices, researchers are looking for ways to detect and track ...
