Dielectric Constant Measurement

The anomalous total electric polarization of 1,4-dicyanobenzene has been shown not to be due to high atom polarization by dielectric constant measurement of the solid substance and by its spectral absorption in the far i.r. However the evaluation of atom polarization from the spectral absorption is questioned because these absorptions have a large temperature coefficient in the 50–150 cm−1 region. The apparent dipole moment of 1,4-dicyanobenzene in solution has been measured and found to be temperature-dependent.

Dielectric Constant Measurement

This paper was developed by microwave measurement on the vegetation dielectric constant through using the rectangular-waveguide at C Band. The measurement system and the method of the measurement will be introduced in detail. We have a standard block of known dielectric constant measurement, and then evaluate the error range. The system of measurement error range is ± 5%.At last, the result of this experiment showed that different density corresponds to different dielectric constant in the case of certain moisture content, and the dielectric constant increases with the density.
