In the closing stage of the synthesis, it is a simple matter to apply (5.69) and
translate the anomalous magnetic field into the anomalous electric field.
Summing up, we arrive at a conclusion that the Wiese-Parkinson matrices given
at all points of the Earth's surface carry complete information on magnetotelluric
anomalies. Using this information with a knowledge of the normal field and the
normal impedance, we can reconstruct the magnetotelluric field and the impedances.
Thus, considering a two-dimensional model and taking into account (5.58), we have

5.2.4 Synthesis of the Magnetic Field from the Generalized
Impedance Tensors
Let the normal field in the generalized impedance model contain three independent
modes: two plane-wave modes with polarization in the orthogonal directions and
the source-effect mode with vertical magnetic component. In that model we have
