PHASE VELOCITY OF ELECTROMAGNETIC WAVES IN THE RANGE 1--25 KCPS,

Abstract

The average phase velocity of electromagnetic waves in the range 1--25 kcps have been obtained through harmonic analysis of radio disturbances recorded simultaneously in Moscow and Leningrad in the daytime from distances r > 1,000 km. The character of the dependence of v/c on the frequency obtained by a method which excludes the source of the signals coincides with the results of preceding projects which take into consideration a standard source. The absolute value v/c within the limits of the precision of the measurements also agrees well. At the frequencies f > 5 kcps the experimental values of v/c, with a precision up to 0.5% coincide with the theoretical ones computed for a plane model of the ionosphere. (Author)
