ELECTROMAGNETIC RESPONSE OF SOIL
Abstract
The possibility of measuring both time-domain and frequency-domain response on small soil samples would allow one to predict the influence of such soil on various types of mine detectors without field trial. We have measured the time-domain soil response on standard cylindrical samples. The time response to abruptly removed magnetic field is similar to 1 / <i>t</i><sup>x</sup>, where <i>x</i> is between 1.1 and 1.3. We have also measured frequency-domain response in the 400 Hz to 480 kHz band by various independent methods and compared with values calculated from the time response. This study shows that for soils with high content of nanoparticles the complete frequency characteristics should be measured instead of traditional two-point measurement.
