We assume that, at the working frequency or frequencies, the wavelength is large compared to the distance between transmitter coil trio and receiver coil trio. This is the quasi-static approximation.
We assume that the coils are so small that their shape does not matter, only their size. This is the dipole approximation. Each coil has an effective-area vector, Aeff_vector, which completely describes a dipole coil's electromagnetic properties.
