PROBING OF A MIXED AQUEOUS SODIUM CHLORIDE AND GLUCOSE SOLUTION WITH THE USE OF A THERMOELASTIC OPTICAL INDICATOR MICROSCOPE

Abstract

In the article, we present a report on the observation of microwave  absorption of sodium chloride (NaCl) and glucose aqueous solution of various concentrations using a thermoelastic optical indicator microscope (TEOIM). The non-invasive sensing technology of TEOIM offers a great advantage over other detection technologies. With the help of TECIM, the change in the distribution of the microwave field was visualized depending on the concentration of NaCl and glucose in the range of $8-14~GHz.$ This article shows the investigation results for various concentrations of NaCl $(0-2.5\%)$ and presents the behavior of average microwave near-field intensity for glucose (varied in the range of $0-10\%)$ and NaCl (fixed at $0.9\%$) complex aqueous solutions.
