| Abstract: | Measurements
of real (ε¢) and
imaginary (ε’’) parts of the complex dielectric constant (ε*) of soil with
varied moisture content have been made at 9.44 GHz using infinite sample
method. The electrical properties of dry soil samples are found to be in good
agreement with the earlier work. The values of ε¢ and ε¢¢ first increase slowly and
then increase rapidly with moisture content. From this data, the ac conductivity
and relaxation time are also reported in the present paper. The result shows
the change in electrical properties of soils before and after the addition of
water. These results provide a basis for using ground-penetrating radar or
other high-frequency electromagnetic sensors in the detection of soil moisture
content. |
