%X We simulate models of anomalous body imbedded in multi-layered medium that include the ionosphere, the atmosphere, and the earth medium by using 3D quasi-linear integral equation method in whole space, and obtain the reasonable resistivity-frequency response of the anomalous body when the bipole length is 100 km, the current is 200 A and the transmitter-receiver space is 1600 km. Through the discussion of the character of resistivity-frequency curves of the targets buried in different depth, we draw the conclusion that the electromagnetic field of the deeply buried anomalous body can be got perfectly when considering the horizontal inhomogeneous complex medium including the large-scale ionosphere and the atmosphere. But the resistivity-frequency responses are different from each other when the resistivity and the buried depth of the anomalous body are variable, which demonstrate the character of the resistivity-frequency of different kind of rock. The results in the paper show that it is possible to distinguish the resistivity of rock from the observed data due to the bipole large power control source (WEM), and the research establishing the basis of the relationship between the electric parameter and rock/medium parameter using WEM observed data.
