Comparative Study of Tissue-Mimicking Phantoms for Microwave Breast Cancer Screening Systems

This comparative study analyzes the dielectric properties of different skin mimicking tissue phantoms for the development of microwave radar prototypes for early breast cancer detection. Therefore, the properties of a fat mimicking carbon-polyurethane-based phantom were verified, and the dielectric properties of three different skin phantoms in four scenarios measured. Furthermore, the dielectric properties were compared to those of the excised human tissue reported in the literature.
