Abstract:

This letter reports a novel in vitro test of blood analysis 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 blood obtained from healthy donors as well as from patients. It is observed 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 is nondestructive in nature. These results indicate an alternative in-vitro method of diagnosing blood abnormalities using microwaves.
