Abstract: This study investigates the use of high-frequency S-parameter analysis to monitor the evaporation kinetics of glucose solutions. By depositing a glucose-containing droplet on a coplanar waveguide transmission line and measuring S11 and S21 parameters in the 100 MHz to 16 GHz range, the authors identified time-dependent dielectric variations correlating with glucose concentration. Simulations confirm that during early evaporation stages, permittivity changes dominate response, enabling clear concentration discriminations, particularly at 15 minutes. These preliminary findings indicate the feasibility of an RF-based, non-invasive method for quantifying solutes in aqueous solutions, with potential applications in biomedical and food industries.
