Dielectric properties of human urine at microwave frequencies

Abstract

Abstract Microwave technology plays a key role in diagnostic and therapeutic medicine. This paper presents a comprehensive study of dielectric properties of urine collected at different intervals of time at microwave frequencies. Measurement is done using cavity perturbation technique at the S‐band of microwave frequency. Urine samples are collected from normal as well as persons with diabetes mellitus and the reported results provide an alternative in‐vitro method of diagnosing diabetes mellitus. The same samples are subjected to investigations in the clinical laboratory for quantitative analysis. © 2004 Wiley Periodicals, Inc.
