The Ionosphere, Skip Distances of Radio Waves and the Propagation of Micro-Waves

Abstract

A detailed description of the Ionosphere is given. From the ionosphere data the skip distances of radio waves are calculated for temperate and tropical zones, with the diurnal and seasonal changes. The values agree with the observed values as far as they are known. It is concluded that daylight short waves as far as thy are known. It is concluded that daylight short wave communication is controlled by the E region in summer and by the F2 region in winter. Theory indicates that the observed bending of micro-waves over the horizon, and hence the successful micro-ray communication to a distance of 200 km, is due to diffraction of the micro-waves over the bulge of the earth, and to temperature gradients in the lower atmosphere.
