A Study on the Frequency Dependence of Electrical Parameters of Soil

초록

This study investigated the frequency dependence of soil resistivity and relative permittivity which were measured by soil type and soil water content. Soil resistivity declined as water content and frequency increased. In particular, the frequency dependence of soil resistivity was significant as water content was low, and resistivity was high. In contrast, the relative permittivity of soil dramatically declined at 10kHz or below as frequency increased, and it revealed the opposite pattern in term of variation patterns, compared to resistivity
