Propagation of LF-MF Radio Waves over Mountain Terrains

A method of calculation of an attenuation function of the ground wave field by means of generalized Feinberg's equation taking into account the mountain relief is considered. It is possible to calculate the electromagnetic field in the LF-MF range over extensive inhomogeneous paths with a "bad" conductivity. Predicting maps of geoelectric sections and topographical digital maps characterizing the terrain relief and different types of forests are the basis for attenuation function calculations
