Abstract :
It is predicted that the future of propagation research and development will involve: 1) world-wide radio communication via satellites, 2) greatly increased interest in the magnetosphere and the solar atmosphere, 3) greatly increased interest in the atmospheres and surfaces of planets, 4) a far wider interpretation of the notion of radio frequency, both at the lower and the upper ends of the spectrum, 5) extensive use of new methods for investigating the top side of the ionosphere by both reflection and scattering techniques, 6) the discovery of new phenomena by the use of large antennas, high-power transmitters and low-noise receivers, and, 7) greatly increased interest in the propagation of sonic and tidal waves in the atmosphere.
