“…Based on this resonator type, three different liquid sensing approaches were developed and analyzed at 10, 35 and 170 GHz with emphasis on the determination of the complex permittivity of liquids of nanolitre volumes. In [Cherpak, 2006] electrodynamics' properties of quasi-optical dielectric resonators of two types with liquid-filled small cavities have been studied. One of the quasi-optical dielectric resonators types is a two semi-disc resonator with a diametrical slot in which a cavity with a thin (0.01  0.1 mm) flat liquid layer is placed and the other one is a disc resonator with a small diameter (0.3  2 mm) cylindrical capillary.…”

The microwave waveguide and resonator methods are compared as applied to the experimental determination of the dielectric properties of high loss liquids. A differential microwave waveguide cavity for measuring high loss liquids complex permittivity in a small volume has been designed and studied. This cavity consists of two circular waveguide cells with central rods made of quartz and surrounded by high loss liquid tested. The cells have different lengths to eliminate complex propagation coefficient measurement errors due to the diffraction effect on the ends of the layered waveguide cells. We have measured the wave amplitude and phase coefficients for the waveguide cavity to estimate physical properties of a high loss liquid under test. The resonant frequencies and the Q-factor of a semi-disk dielectric resonator with high loss liquid filling a capillary have been measured. We have selected water-ethanol solutions as a high loss liquid under test for both techniques. We have determined the measurement sensitivity for these two techniques. The measuring results are discussed. Both the waveguide and resonator methods provide comparable sensitivity and can be successfully used for the complex permittivity characterization of high loss liquids in small volumes.
