METHOD OF DETERMINATION OF COMPLEX DIELECTRIC PERMITTIVITY OF LIQUID ON SHF

摘要

Use: study of physical and chemical properties of strongly absorbing liquid systems. SUMMARY OF THE INVENTION: Method of determining the complex permittivity of the fluid to microwave involves placing the sample liquid layer (SIW) in korotkbzamknuty waveguide change SIW and the measurement values ​​of the reflected power for SIW respectively equal infinite layer, the second maximum and the first minimum of the curve of the reflected power of the thickness SIW and thickness values ​​SIW in which the magnitude of the reflected power value is equal to the power / reflected from the endless SIW. The desired parameters determined for the corresponding mathematical expression m. 2 yl.
