In 1902 (independent of A. E. Kennelly) he suggested the existence of an atmospheric layer that reflects radio waves back to earth (1850-1925)

Usage examples of heaviside.

British scientist and mathematician Oliver Heaviside, whose untidy theories and formulas made long-distance telephone communication possible.

With the right machines, we can transform the Heaviside Layer into a shield that will perfectly insulate this planet against the cosmic cloud.

From these globes the atomic energy would flame out, to encircle the planet and transform the atomic structure of the Heaviside Layer into an impregnable barrier.

Guy down through the Heaviside layer, but forced him into fawning agreement.

Dest had no relay satellites or Heaviside layer, so any sort of broadcast communication was limited to line of sight.

XV TELEGRAPHING WITHOUT WIRES The First Suggestion--Morse Sends Messages Through the Water--Trowbridge Telegraphs Through the Earth--Experiments of Preece and Heaviside in England--Edison Telegraphs from Moving Trains--Researches of Hertz Disclose the Hertzian Waves.

Working together, Preece and Heaviside extended the distances over which they could communicate.

As I understand it, he gets directional signals from a diagonally upward direction, but they could be sent from somewhere near here and bounce off the Heaviside layer so as to strike his antenna from that angle.

Promethean found it, and signals broadcast from New York and London to the relay ships beyond the Heaviside layer brought little hope.

You can count on their reflexes to bring you safely through the perils of the Heaviside Layer, the Van Allen Belts, and meteors thick as flies around a hog.

Depending on the hour, the tilt of the planet, the angle of the sun, the cosmic rays, the aurora australis, and the Heaviside layer, he was able to get anywhere from eighteen to thirty-six different news broadcasts every day, from all over the world, though naturally, like most of the world, he favored those of the BBC.

Radio would be line of sight, and the Ringworld atmosphere probably had a Heaviside layer.

They are already in operation, sending their defensive waves against the Heaviside layer.
