Experimental research of dielectric dispersion property in radio frequency

By analyzing the relationship between the dielectric constant to salinity,water saturation etc.at different frequencies,the analysis suggests that in low water saturation condition,the dielectric constant decreases with the increase of salinity and when water saturation reaches a certain degree,the dielectric constant curves of different salinities are basically coincident.Meanwhile,the relations in terms of changes of the frequency-dependent dispersion amplitude and the frequency-dependent dispersion coefficient with various salinities and water saturation are established.The relationships between the dielectric constant and various factors are clarified.When the water saturation is higher,the dielectric constant and the degree of dispersion are bigger.
