Abstract

Microwaves play a vital role in the diagnosis and treatment of diseases caused by the abnormal mineralization of biological fluids in human body. First hand information regarding the dielectric behavior of these minerals facilitates to detect these crystals. This paper attempts a comparative study of the dielectric properties of urinary crystals grown in vitro by gel technique with natural stones procured from patients who had undergone stone removal surgery. Cavity perturbation technique was employed and measurements were made in the S band. Β© 2002 Wiley Periodicals, Inc.

The relative permittivity and conductivity of rabbit eye lens were measured in the frequency domain between 2 and 18 GHz at temperatures of 37 and 20 " C . An analysis of the data suggested that a significant proportion of the bulk water in nuclear and cortical lens tissue may behave differently to

The in vitro dielectric properties of human fetal organ tissues were measured in the frequency range from 100 kHz to 500 MHz at 24 "C. The dielectric measurements were performed by using a network analyzer (HP4195A) and a coaxial line capacitive sensor. The tested samples, including skin, muscle, he
