Hi,
I would like to know if it is possible to calculate the dielectric constant of a pure fine sand if we know its moisture content. Does it need a lab work or no? If anyone know how to do that, I would be much appreciated.
Looks like other people are doing experiments, check:
Measurement of complex dielectric constant of sand and dust particles as a function of moisture content.
Abstract:Experimental Investigations were carried out to measure the complex dielectric constant of dry and moist soil samples (sand, silt & clay) at 10.45 GHz in bulk concentration. The complex dielectric constant is found to depend heavily on moisture content. Finer dust particles (clay) show higher dielectric constant than coarser ones (sand & silt) in dry sample. The effective increase in complex dielectric constant with same moisture content in sandy samples is greater than clayey and silty sample. Two distinct regions are clearly observed in the variation of the complex dielectric constant with moisture.
