Application of Disk-Containing Quasioptical Dielectric Cavity Resonators for Investigating Two-Component Aqueous Solutions in Small Volumes
要約
The paper presents results of experimental investigations of quasi-optical disk-containing dielectric cavity resonators with the capillary filled by a binary solution based on a lossy liquid component (water). Ethanol and acetone were used as the second component of the solution. As has been found, many features of the cavity's eigenfrequency and Q-factor dependences upon concentration of one of the solution components which were measured for the water-ethanol solution, are well correlated with calculated values of the dielectric constant. The measurements were conducted at the frequencies 37 to 40GHZ for the HE whispering-gallery mode excited in the cavity. The investigated cavity resonator could be used as a cell for measuring characteristics of solutions in small volumes.
