The microwave measurements were performed by rectangular cavity perturbation method in the S-band of microwave frequency with the blood plasma collected from normal rats (Controls) as well as chemically induced rats (Aβ). A change is observed in the dielectric properties of the Aβsamples but not the controls samples at the extended period of time. This measurement technique is simple and the collection of blood from the rats is nonsurgical in nature. These results prove a new method of diagnosing Alzheimer’s Disease (AD) using microwave techniques.展开更多

The measurements were performed using a rectangular cavity with the perturbation technique at the S-band of microwave frequency with fresh juices made instantly from the fruits as well as collected from the packed fruit juices available in the market with the normal added preservatives in order to keep the increase of the shelf life. From the results, it is observed in the certain dielectric properties, the fresh juices samples and packed juices samples were varying and also varying over a period of time. This measurement method is simple and quick and can be used over a range of juices. These results prove a new method of determining the quality control of juices using microwave principles.展开更多

The experiment was performed by cavity perturbation method in the S-band of microwave frequency with the pericardial fluid from healthy persons as well as from patients suffering from pericardial bleeding. It is noted that considerable variation in the dielectric properties of patient samples with the normal healthy samples and these measurements were in good agreement with clinical analysis. This measurement technique and the method of extraction of pericardial fluid are simple and both are non invasive. These results give light to an alternative in-vitro method of diagnosing onset pericardial bleeding abnormalities using microwaves without surgical procedure.展开更多

The measurements were made using rectangular cavity perturbation technique at the S-band of microwave frequency with the different samples obtained from healthy donors as well as from patients. It is observed that an appreciably change in the dielectric properties of patient samples with that of nor-mal healthy samples and this measurements are in good agreement with clinical analysis. These results indicate an al-ternative in-vitro method of diagnosing thyroid abnormalities using microwaves.展开更多

This paper presents a new method of detecting H1N1. The dielectric properties respiratory mucus is studied at microwave frequencies using rectangular cavity perturbation technique at the S-band with the different samples of respiratory mucus obtained from healthy donors as well as from patients suffering from H1N1. It is observed that an appreciably variation is found in the dielectric properties of patient samples as that of normal healthy samples and this measurements were in good agreement with the clinical analysis. This measurement technique is quick, simple and suggests a new novel method of diagnosing H1N1 using microwaves.展开更多

The cavity perturbation technique in the frequency range between 2 and 3 GHz was used in this study. It is observed that the dielectric constant of pregnant women’s blood samples is higher than that of non-pregnant women’s blood samples, and the conductivity of pregnant women’s blood samples is higher than that of non-pregnant women’s blood samples. This is a novel in-vitro method of determining pregnancy. The same samples were also subjected to investigations in the clinical laboratory for quantitative pregnancy blood tests. Determination of pregnancy will help the woman to make preparations for proper prenatal care or family planning.展开更多
