Description
Summary:In this work we present a microwave intracavity sensor for the characterization of aqueous solutions of nano-liter sessile droplets, deposited on the microstrip line electrode. The sensor operates at  frequency and is based on tunable magnonic delay line oscillator. The samples were characterized by using their evaporation dynamics, by measuring their dielectric constants. The experiments have shown that the sensor is capable of detecting the salinity (S) of water with the required precision and resolution. The advantage of the sensor is the possibility of measuring the parameters such as S, Total Dissolved and Total Suspended Solids, simultaneously.
