Deviation at Vertical Incidence in the Ionosphere

Article metrics

Abstract

WITH regard to G. Millington's communication1, we should like to point out that, so early as 1946, we directed attention to this phenomenon and set up the differential equation of the ordinary and extraordinary rays. We calculated the deviation for a vertical sounding made in Paris on 5 Mc./s. and found it equal to a few kilometres. We also suggested the use of this deviation for explaining the relative variation of amplitude of split echoes2,3.
