FREQUENCY DEPENDENCE OF IONOSPHERIC ABSORPTION
Abstract
The magneto-ionic theory is examined in its relation to absorption calculations. For representative profiles the complex index of refraction was computed using the Appleton-Hartree and Sen-Wyller magneto-ionic formulas. The height profiles of the real and imaginary part of the index of refraction are plotted and the absorption corresponding to day-time and night-time conditions is computed and its frequency dependence determined. It is determined that absorption for general conditions also follows closely an inverse square law, although there are deviations, particularly for the extraordinary ray. It is determined that general propagation conditions do not affect radically the possible use of differential absorption for total absorption measurements. A possible method for doing this is given. The variation of the absorption coefficient as a function of parameter N is also determined and a linearity condition is shown to hold under certain conditions for general propagation conditions.
