The search for intermodulation coupling in the ground
The assumption that the ground behaves as a linear electrical network is tested with a field experiment. Two sinusoids of current are transmitted into the ground simultaneously. The potential field is measured and recorded on magnetic tape. Amplitude spectra are computed and searched for intermodula...
