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 ...

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 ...

AM waves, which have a lower frequency, are attenuated when they are refracted from the ionosphere or the Earth’s surface, resulting in shorter travel distances than shortwaves. Shortwave radio ...

By leveraging the reflection of electromagnetic waves between the ionosphere and the Earth's ... Among them is the Circular Array Solar Radio Imaging Telescope, the world's largest aperture ...
