... field (?T or vertical magnetized field) may lead to erroneous results, and hence it provides false information for the interpretation. This is because magnetic field has more complex relationship with anomalous body compared to the gravity field. In this paper, we propose a modified edge-enhancement...

... of the anomalous body. The back- ground conductivity can be simple, such as a uniform or lay- ered earth in which the solution can be derived (semi-)analytic- ally, or it may be more complicated and require numerical modeling. The EM fields from any conductivity are found by solving the quasi-static Maxwell s...
