Abstract :
The ionosphere, the region of the upper atmosphere, varies strongly with frequency; this provides some properties in the ionosphere region which make radiowave propagation more complicated. We propose a new method, based on phasors of the voltage, V, and on the solution of the Laplace equation, to compute the effective B in arbitrary points of space. This method is implemented easily and solved in different conditions.
