SENSING OF SODIUM CHLORIDE AND GLUCOSE MIXED AQUEOUS SOLUTION BY USING A THERMOELASTIC OPTICAL INDICATOR MICROSCOPE

Abstract

In the article we observed the microwave absorption of sodium chloride (NaCl) and glucose aqueous solution with different concentrations by using a thermoelastic optical indicator microscope (TEOIM). The non-invasive sensing technology of TEOIM is giving a big advantage compared to other detection technologies. By a TEOIM were visualized the change in distribution of microwave field depending on concentration of NaCl and glucose in $8-14~GHz$ range. This article is shown the investigation results for different concentrations of NaCl $(0-2.5\%)$ and represented the behavior of averaged microwave near-field intensity for glucose (varied of $0-10\%$ range) and NaCl (fixed at $0.9\%$) complex aqueous solutions.
