A study of dielectric properties of fatty, malignant and fibro-glandular tissues in female human breast

In this paper, dielectric characteristics of fatty, malignant and fibro-glandular tissues cultivated using the xenograft method were analyzed. Since the tissues were extracted from the mouse just before the measurements, they were maintained as fresh as living tissues in the measurements. This allows as to get more accurate and reliable results. Dielectric properties of fatty, malignant and fibro-glandular tissues were measured in the frequency range between 50 MHz and 5 GHz using open-ended coaxial probe and two-port sample holder. For the measurement of the dielectric properties, 10 xenografted samples were used. From the measurement data, the dispersion characteristics of the measured tissues were modeled using the Cole-Cole model. Breast cancer tissue showed a quite different dispersion characteristics compared to normal tissues.
