Abstract
This paper reports a novel in vitro analysis of urine based on the measurement of the dielectric properties at microwave frequencies. The measurements were made using rectangular cavity perturbation technique at the S-band of microwave frequency with the different samples of urine obtained at different intervals of time from healthy persons as well as from patients having diabetes mellitus. It is found that an appreciably change in the dielectric properties of patient samples with the normal healthy samples and this measurements were in good agreement with clinical analysis. This measurement technique an alternative in-vitro method of diagnosing diabetes mellitus using microwaves.
