For some time, whole space feature as a theoretical problem has been a puzzle in mining transient electromagnetic method (TEM). We have introduced a detailed method of calculating the transient response of a vertical magnetic bipolar source in a whole space plane layered medium in order to obtain whole space features. After designing a whole space plane layered medium model, equations were established based on boundary conditions in terms of electromagnetic vector potential. Expressions of electromagnetic f...

1 Introduction The distributed feature of a whole space geophysi- cal field is an inherent special academic issue of geophysics in mining. At present, the TEM in mining, using the basic theory of ground TEM as explained in references, is one of the most w
