Propagation of electromagnetic waves in the stratified stomosphere without the negative gradient of the modified refractive index is considered. The received fields propagated from a vertical magnetic dipole situated in such an inhomogeneous atomosphere are expressed as a sum of modes. The complex eigenvalues and eigenfunctions of modes can be calculated from the mode equation obtained with analytic solutions to the wave equation. In practice by the inhomogeneous atomosphere which is 20-30m thick with the rapid gradient of the modified index, the field strength for frequencies of 3-10 GHz is received at a noticeably small attenuation rate in proportion to the distance from the earth surface.
