- Sky waves are electromagnetic waves transmitting antennae emit and then receive after being reflected by the ionosphere. This method of propagation is known as sky wave propagation. The ionosphere’s entire internal reflection of the electromagnetic waves causes the skywaves to propagate.

What is Sky Wave Propagation? Sky Wave propagation, commonly known as the skip, is a kind of radio wave propagation. It is either the reflected or refracted back waves to the earth from the ionosphere, which is an electrically charged layer of the upper atmosphere.

What does skywave mean in radio communication?
In radio communication, skywave or skip refers to the propagation of radio waves reflected or refracted back toward Earth from the ionosphere, an electrically charged layer of the upper atmosphere. Since it is not limited by the curvature of the Earth, skywave propagation can be used to communicate beyond the horizon, at intercontinental distances.
Definition: A type of radio wave communication in which the electromagnetic wave propagates due to the reflection mechanism of the ionospheric layer of the atmosphere is known as sky wave propagation.
Jul 10, 2023 · Sky wave propagation, also known as ionospheric propagation, is the mode of propagation in which electromagnetic waves emitted from an antenna and directed upward at great angles are reflected back to earth by the ionosphere.

The propagation of sky waves (also called ionospheric waves) revolves around the refraction mechanism in the ionosphere. The electromagnetic waves are launched towards the ionosphere wherefrom, under suitable conditions, they return to the earth due to the refraction mechanism.
