Abstract: The attenuation of the VLFradio waves in the Earth's ionosphere is analyzedand computed. Using the Fourier Tansformation, one may obtain the formulation which indicates the attenuation changing with ionospheric collision frequenciesand the geo-magnetic orientations. Numerical results of the relations between theattenuation and the ionospheric collision frequencies under several geo-magneticorientations are given.
