Quasioptical multilayered interferometer for gasoline testing

Results of an experimental study and a calculation of the quasi-optical multilayered structure formed by an adjustable dielectric interferometer and a liquid investigated filling its gabs are presented. It is shown that this structure may be used for quality tests of liquid petroleum products, for measurement and investigation of physical parameters of liquid media in the millimeter wavelengths region. This structure is realized practically in the form of uncomplicated adjustable quazi-optical quvette filled with liquid and connected with beam-guiding elements. Comparison of experimental data with theoretical calculations gives us the opportunity to choose a value region of the values for the physical parameters interesting for us for each material under investigation.
