marconi’s curved radio wave

articles_marconiCurved Radio was named after the curved radio wave that Guglielmo Marconi invented to go around obstacles.

From the Time Magazine article dated Monday, Aug. 22, 1932 … in the Science section titled: Curved Radio:
“Long-wave radio signals spray out from the transmitters in undulations from 200 to 25,000 metres in length. They surge through & around obstacles or up against and down from the ionized Kennelly-heaviside layer of the stratosphere. Short radio waves are not so fluid. Like light waves, which are very much shorter, short radio waves travel in straight lines only.”
