Abstract A simple method for measurement
of the dielectric properties of plant leaves at microwave frequencies is
described. Theoretical analysis is given of the frequency dependence of the
reflection coefficient of a sample holder with a sample located at the end of
the coaxial line which opens into a circular wave guide operating below
cut-off. Analysis and calculations of the uncertainty in permittivity
measurements, as well as experimental results for rape leaves, are presented
and the limitation of the method are discussed. |
