Method estimating integral mean value of enhancement factor and path latitude for whistlers below magnetic latitude 10 deg
Abstract
The propagation of whistlermode waves in the ionosphere is assumed to be ducted propagation. In other words, the waves will be presumed as traveling along magnetic field lines. An analytic solution of the whistler dispersion equation is obtained in terms of the electron density models of the ionosphere, the transverse gradient of the electron density required for guiding whistler mode waves along a magnetic field line, and an empirical formula for the magnetic field lines of the 1980's IGRF (n=8). Here, the electron density enhancement factor is defined as N sub c/N sub g1. N sub c is the electron density at the center of the duct; N sub g is the background electron density at the latitude where the duct center lies. Thus, the integral mean value of the enhancement factor required and the path latitude can be analytically determined by a set of observed values: N sub m F2 and h sub m F2 of the ionosphere, and D (whistler dispersion).
