The MT interpretation allows easy geophysical survey design including coordinate systems, geographic survey directions and true electric bipole receivers with actual survey lengths. Thus, it allows for correct integration of the electric fields along the receiver while also facilitating true calculation of induction effects in the modeled electric fields.
