The measurement and model construction of complex permittivity of vegetation

Science China Earth Sciences, 2013
The complex permittivity of targeted objects is an important factor that influences its microwave radiation and scattering characteristics. In the quantitative research of microwave remote sensing, the study of the dielectric properties of the vegetation to establish the relationship between its specific physical parameters and complex permittivity is ...

Measurement of complex permittivity of liquids at microwave frequencies

Journal of Physics E: Scientific Instruments, 1969
The effect of lossy short-circuiting plungers in permittivity measurements involving variable line lengths is discussed. It is shown that, in some cases, neglecting the resistive component of such plungers can lead to errors as high as 20% for the dielectric loss.

Versatile cell for complex permittivity measurements on liquids

Review of Scientific Instruments, 1999
A disk type guarded measurement cell is described, which permits the determination of the complex permittivity of liquids with an accuracy of 0.5% or better. The cell has small residual circuit elements (4 nH and 20 mΩ) and behaves like an ideal capacitor for radius-to-electrode spacing ratios ranging from 15 to 135.
