| Abstract: | The real (ε′) and imaginary (ε′′) parts of
the complex dielectric constant (ε*) of soil with varied moisture content have
been determined experimentally under laboratory conditions at 9.44 GHz using infinite
sample method. The value of ε′ and ε′′ first increases slowly and then rapidly
with moisture content. From this data, the ac conductivity and relaxation time
are also reported. The result shows the change in electrical properties of soil
before and after the addition of water. These results provide basis for using
ground penetrating radar or other high frequency electromagnetic sensors in the
detection of soil moisture content. |
