Nikola Tesla - Wave Propagation — Wave Propagation — A large number of things—some desirable, some not—can happen to a radio wave on its way from one place to another.

Sky wave propagation is dependent on reflection from the ionosphere, a region of rarified air high above the earth's surface that is ionized by sunlight (primarily ultraviolet radiation). The ...

The exercise challenges competitors with voice and data contacts between domestic and international teams via HF sky-wave propagation. ... "If the satellites fall out of the sky, cell towers go ...

This is called sky wave propagation. It’s often referred to as “the skip.” Because of the skip phenomenon, if all AM stations operated the same at night as they did during the day, there ...

Abstract. The strength of the low-angle sky waves radiated by a medium-frequency aerial depends on the conductivity of the ground extending for many wavelengths in the direction of propagation.
